Firefox コミュニティフォーラム

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

i need to copy and paste text that's also a link, but firefox isn't letting me highlight it, I can do it in chrome, brave, & opera, it's not a mouse problem either, if I just right click on the page and select "highlight all" FF wont highlight it, is there a setting for this or a extension I can download? (in the picture the the rad text is also a link, I need to copy the number portion)

I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

In Firefox browser , truncation of string is not working, when typing into the input box at first time truncation is not working, but when focusing out and typing once again it start working , seems its rendering problem which is not working at first time.

I am using following code <style> input.b { white-space: nowrap; width: 50px; overflow: hidden; text-overflow: ellipsis; border: 1px solid #000000; </style>

text-overflow: clip (default):

Above code will give the different result in firefox and the the chrome browser.

in chrome it will work at first time , means once user will start the typing into the input box , it will start showing the ellipses once text overflow will happen. but in Firefox it will not work like this, at first time when user will start the typing it will not show ellipses although text exceeds the boundary of input box , but when user focus out from the input box and start once again start typing into the input box ellipses will be shown. this behavior is creating confusion.

Kindly provide the solution for the same I am using 128.5.2 esr firfox version

I am on a school site and frequently download Word documents. Prior to a recent update ( this summer) the files went to a download manager and I could either work o the document or continue to work on the current webpage. However, sionce the update, the docuemnt is saved but inthe process I am kicked off the current webpage. Should I revert back to a previous version of Firefox or is there a workaround or patch? Thanks

I have the last Firefox version and am trying to add extensions (e.g. video download helper). When I click on Add to Firefox, it works at loading the extension, but without any success. The blue dot in the gray square dances and dances and dances.... Thanks !!

I've got Firefox on three devices and I'm looking to get a little more fine grained control between the synced data.

Ideally I want to sync passwords between all three but only sync bookmarks between two of them. This doesn't seem to be possible with the current options. Is there an alternative short of manually exporting and importing on the devices I want to keep in step?

I have been facing a problem with custom images of home page shortcuts. Whenever my laptop shuts down and Firefox was open at that time, then upon restarting, Firefox recovers the websites that were open before shutting down. However, in this process, the shortcuts do not load the custom images at all - they are all blank. I created a new profile and started everything from scratch then also the issue was there. Is there any solution to this, or is there any issue that might be from my end?

I collect images ... when I download an image there is a series of numbers below the image ... over the years I have noticed the numerals have vastly increased in quantity ... there are now as many as 37 numbers under each picture I download ... it is very tedious to reduce or erase these numbers for every image downloaded ... obviously there is some sort of "counter" built into the browser ... Is there any way to reset or eliminate this counter ? ... Thanks ...

I'm trying to import my passwords; what I've read says I will find Logins and Passwords in the menu represented by three bars at the top right of my foxfire sign in page. The problem is I have three dots, not three lines, and nowhere do I see Logins and Passwords, just Passwords, and there's no import data option there. Sorry if this is lame. I'm old and clueless in the world of tech. Also, thanks for any assist.

Bonjour,

dites, j'en viens à venir ici demander si il est normal que je doive activer manuellement la synchronisation à chaque ouverture de firefox developer edition en 64 bits svp ?

Aussi, depuis quelques jours, il semblerait que je doive réparer firefox pour pouvoir acceder à mes pages ....

Jamais eu de souci jusqu'à maintenant mais c'est un peu redondant comme process ...

Merci de vos eclaircissements !

I've been a loyal user of Firefox for many years, but recent problems have cause me to question that loyalty. I posted previously that the Alarm.com web site does NOT appear correctly AFTER login (NOT BEFORE login). NONE of the suggestions that were given helped. Now I see that images don't appear on a matchmaking site I go to, either on the site itself or images from the site in Outlook web (ie using Firefox) email. It never used to be this way. I never had to worry about it. I've made no changes to Firefox that I'm aware of that would cause this change in behavior. WHY is this happening? I tried everything but creating a new Firefox profile suggested in this link:

https://support.mozilla.org/en-US/kb/fix-problems-images-not-show#w_im-still-having-problems

NOTHING works. I don't get it. Images show with no trouble in Edge. So does Alarm.com.

On YouTube tabs, if Firefox memory usage starts climb (ie. more than 3-4 tabs active), there are janks for a few seconds preventing me from interacting with the YouTube tab. This jank does not happen with other tabs (can even interact normally with other tabs while the YT tab is janking). Attached is a profiler report.
