Home screen shows: Error: Platform version '130.0.1' is not compatible with minVersion >=130.0 maxVersion <=130.0

My account indicates I am up to date with version 134.0.2 (64bit)

In addition, today all tabs are broken

I can't log in to certain sites even though they've been on my favourites list for years, i.e. bank account and grocery shopping. I can log in to them using Edge , so what's gone wrong with Firefox. Is the latest updates to blame ???

I have tried everything I can think of or find on the internet about changing fonts on FireFox. My bookmarks and titles are very large and I can't get them down at all. I've tried all the suggested way on the internet by changes the fonts in settings/General but it doesn't change the font in Bookmarks. Help, I'm loosing a lot of real estate on my browser

secure.chase.com has been broken for some time. The site works with other browsers on the same MacBook Pro (2017) under Monterey Does not work in Firefox, even in "troubleshooting" mode with all plugins disabled.

Please help

Thanks, Walt

I'm looking to change all the fonts on my Firefox webpages and menus to Lexend. How would I do this? I've changed the majority of it in Settings > General > Language and Appearance > Fonts, but I'm looking to change the font in my search bar, on my tabs, and other menus like the Extensions popup.

It would be really helpful if all these settings were in once place, as well!

Vert Scroll bar , right hand side are too narrow and need to be widened. Where is the setting to achieve this? FF scroll bar does not follow windows defaults either.

A post similar prev, has been archived -not viewable & reports to ask new question.

Question self answered

Running MAC Ventura 13.7.3 See Attached. All language choices are set to US English, unless there is a double secret location. It's been going on for months, over various versions of Firefox and ventura. They usually only come up when I first load Firefox, and they acn come up on different pages. How do I stop this annoyance? I've cleared cookies and that did no good Thanks

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

updated and uBlock off, when i click and drag down, I can't go below the taskbar like I can on my phone (and used to be able to on my pc. Also, no matter what deviations of directing my downloads, whether I specify target or 'always prompt' ALL downloads go to Documents or Temp files. Then I have to cut and paste correct location. Reported THIS several times to no resolution. Tired of backing up and reinstalling FF over and over! Thanks

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works

ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

Hi. Just recently firefox, which has been faultless for a long time, is now occasionally giving me "hmm, cannot find this site" messages for Google and BBC. Duckduckgo and chrome are operating normally.

What is the cause of this aberation?

Hi there! Ever since I believe two days ago, playing videos in the Firefox browser have been giving me issues. Videos often end up looking scrambled/glitchy. It starts off mostly in green but sometimes turns multicolored, and the tab the video is in starts lagging or freezing. At first I thought it was a YouTube issue, but it's happening on other websites as well, even for animated gifs. I tested some videos in Edge, and so far I haven't had any glitchiness there yet.

I currently have Windows 11, and Firefox is up-to-date. I've attached screenshots from three different websites. Happy to provide other info if needed!

Firefox 134.0.2

Hi!

I was shocked when I recently visited a website of a company that offers IDEs. I've downloaded one of the IDEs a couple of weeks ago and now that I've came back to the website looking for plugins, the website still "knew" which version of the IDE I had downloaded because it gave me warnings about plugins not compatible with my IDE version. Now: My privacy settings in Firefox are "strict", the option "Delete cookies and site data when Firefox is closed" is checked and I've closed Firefox several times in the meantime. Still, the website has information about my identity.

I would have expected that with these settings something like what I've described wouldn't happen. I must say, I'm quite disappointed. Is there anything else that I can do within Firefox to enhance my privacy?
