I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

refer attachment, i am unable to access this site. completely working fine in edge. what could be the issue as i reinstalled firefox and still is facing the issue.

I was using the control key with single word urls, like "nfl," as a shortcut to go to nfl.com. That had been working until the most recent update, albeit with a right-click menu appearing after Firefox opened the desired page. Now, when I hold the control key with the location bar active, Firefox brings up the right-click menu without going to the desired page. For example, if I enter nfl.com and hit ctrl-enter, the browser stays on the current page and brings up the right-click menu even though I'm not clicking the mouse. Is this a bug or new behavior. (Note: I have Firefox set to autocomplete only bookmarks.)

Hello, I have restarted my laptop only to find that my previous session was not retriavable anymore, so I went to my History and to my utter surprise it was gone. Years of history deleted. Could you help me understand what on Earth just happened?!?!?! Thanks in advance

For many years now I've had Firefox clear

• browsing & download history
• temporary cached files and pages
• saved form info

but not

• cookies and site date
• site settings

This worked flawlessly until Firefox updated to version 136, at which point all cookies were deleted and I was signed out of every account on every website.

Looking at the settings page, the option to delete cookies and site data when Firefox is closed is now enabled. I don't remember what this setting used to look like, but I did not change it recently.

Unchecking the box seems to work, but I shouldn't suddenly have to do this, and the "damage" is done.

Why did the update to version 136 sign me out of every website, and how do I protect myself against this happening again?

Hi,

I have a question to the Firefox Snap permissions. I want to give Firefox the minimum of permissions which you can grant via Settings => Apps => Firefox Web Browser, because of security reasons.

So, a lot of them are self-explanatory, but there are some where I can’t imagine what that means and whether Firefox really needs such permission to run correctly and save or not. These are the following:

- Run in Background - Detect network devices using mDNS/DNS-SD - system-files - gsettings - Access hardware information - Mount-control - login-session-observe - opengl - system-packages-doc - Read/write access to U2F devices exposed - Access energy usage data

So, my question is: Does Firefox really need one of these above permissions to run correctly and save (I am asking because I don’t know if some of the above permissions are for security reasons activated) or can I turn them off?

Thank you!

Recently, whenever I access a local TV stations news post and try to read it, I get the pop-up shown in the attachment. Why is it happening and what can I do to eliminate it?

My Firefox window keeps expanding to fill the entire computer desktop. I make it smaller, and it expands again. How can I fix this? I like to be able to adjust the size of the window manually and have it stay that way!

For the past few days when I use Firefox and Thunderbird my entire screen will randomly start to flicker, at times very quickly and rarely the entire screen goes black for second or two. This behavior immediately stops when I close the app. It does not happen with any other app. I've tried disabling hardware acceleration in Firefox and that didn't help. Both apps are on the latest version and I also updated my video driver. Tried removing the two add-ons I have. I'm on Windows 11 Firefox 136.0.

Hello,

I'm new to Firefox after changing from another browser.

I am looking for a setting to turn on notifications from sites such as Instagram to notify me with a pop-up window from the web browser.

Is this not available on Firefox?

If not available, I'd like to suggest this as a new feature.

If it is available, would someone help me find this to turn on when I signed into Instagram? It did not ask me if I wanted to turn on notifications.

Thanks

Hello, I just updated Firefox to version 136 on my MacBook Pro. I was playing a 4k YouTube video, and at 16 minutes and 10 seconds in the video froze. If I moved the cursor the pause button and all of that would come up at the bottom, but when I clicked on the option to exit full screen it did not respond. I pressed the escape button and that did get me out of full screen, but the video window did not apply the right formatting. I'll include a screenshot so that you can see what I am talking about. After exiting full screen, if you look at the bottom of the video window, the option to go back to full screen is cut off. Closing Firefox and relaunching it appears to have things working again, at least for now. I thought it would be best to report this just in case it isn't an isolated glitch.

Hi, I use Firefox all the time, love it. But I have noticed a problem.

If I have say 7 tabs open, none of them doing anything, then go away from my laptop for say 20 minutes, when I come back the fans on the laptop are screaming. Even if it was minimise.

I have a fairly modern laptop Dell GSeries1522, 12th gen processor, 16gb ram, i7.

I have tested this issue using Edge and Chrome with exactly the same tabs open and the laptop is all quiet. I'm on the precipice of moving to Edge. Happy to provide more information. Task Manager now shows FF using 1223.0mb of memory, Edge 466.7mb. They are both in "efficiency mode".

Any help or advice would be great.

I already have "Automatically install updates" and "When Firefox is not running" enabled.

But after each Firefox update I still get the "Do you want to allow this app to make changes..." prompt and "Firefox is installing your updates and will start in a few moments" window. These are inconvenient as they require user input and take up time.

I don't get these on all other browsers I use (including Chrome, Edge, Safari, Firefox, Opera, Vivaldi, Brave), which all update in the background seamlessly.

Is there a way to prevent these in Firefox and just have Firefox update seamlessly in the background like other browsers?

I use firefox beta and noticed that firefox always closes exactly when a new hour hits. The moment it hits say exactly 4:00, 5:00, 6:00, or so on for every hour of the day, the app crashes. I also tried this on the standard firefox and the same thing happens. I even decided to alter my device time in settings and set the time to 11.59 only to have the app crash the moment it turns 12. This is the same for any other time of day I set. I tried changing battery optimization and storage restrictions/optimization and nothing seems to work.
