Due to some unknown reason from today morning whenever I use paste function, my Firefox crashes and quits. It includes pressing ctrl+v, right click and paste, and edit>paste. It occurs in all webpages and not only with texts, but also when I try to copy/paste for example a bookmark.

My browser is up to date, I rebooted several times, and also opened Firefox in Troubleshoot mode. But the crash still happens.

Does anyone have any idea what the reason of this problem is and how I can fix it?

I use multiple desktops on Windows 10; usually between two and four at a time. Each of those desktops has multiple Firefox windows open.

Whenever I restart my computer (which is not often but it happens) Firefox restores all the previously opened windows onto a single desktop, leaving me to sort out the mess. Firefox also re-opens windows/tabs recently stashed using the Tab Stash extension.

Is there anything I can do to make sure Firefox remembers which windows belongs on which desktop, and to keep stashed windows closed?

What configuration setting do I adjust if I want to change the font size of only the tabs and toolbar text, not the text of the window / body (managed with Windows' "Make text bigger" option)? I've made the text of the tabs and toolbar large enough for my taste, yet that same setting make the text for everything else in the browser way too big. I'd rather not download a third-party extension as the solution as that implies third-party data gathering. Thank you.

I have a vision problem and can only read if dark mode is on. I have dark mode on for firefox but when I go to a website from settings, the back ground is white and blinds me. help

My IDM extension no longer seems to be the default downloader. Downloads now come via the native Windows (8.1) downloader. Can you suggest any way of resolving this issue?

I believe this happened after some Windows update.

Neither in Firefox, nor in Chrome can I get my microphone to work. The browsers are correctly asking for permission to access the microphone, apparently the website gets a positive feedback, but no audio stream.

For example, if I use the online microphone test, the test widget displays a line, but no visualisation of my speaking. https://www.onlinemictest.com/

The webcam works fine, and the microphone does work in other applications.

Teams Web even allows me to switch Microphone from my headset to the internal mic, but it doesn’t change anything.

Might there be some Windows Policies in play that forbid browsers in general to access the microphone?

How can I further analyse this issue?

Thanks a bunch already!

Hello, in version 112.0 editor.use_div_for_default_newlines in FALSE it does not work. When I write in certain forums, it creates a double space between lines, any help?

It worked until today when i update it.

Thx.

please note it seems possible that this category is specifically for download of firefox, this is not so. opting for this category given the possibility that that theory is mistaken, and due to not seeing any other category that might be more suitable

using firefox developer edition (also couldn't find an individual category for this), and when downloading any files, it saves automatically without asking where/what to name it etc., as preferred. but specifically for pdf files, it always opens them in a new tab upon completing the download; this can be very frustrating when downloading larger quantities, especially with it switching to that file tab and away from the source of downloading. firefox is not even the default for opening pdf in the first place

looked through preferences for anything (and tested anything that looks potentially relevant, to no avail), looked for a solution online from various sources and search methods, no dice

how can this be disabled?

Greetings everyone,

I accidentally double clicked on "Downloads" after accessing the "Tools" menu so all of my downloads in the "Downloads list" is now gone... :(

I know that the actual files aren't deleted but I can no longer see the location of the files I've recently downloaded :( :(

Thank you for any help!

As per old thread at: https://support.mozilla.org/zu/questions/1365405 which has since been archived.

As of version 113, this solution is being suppressed. I occasionally see the x appear briefly on the left when a tab is selected, but then it reverts. So far I have not been able to work out what setting is overriding this function, so I've just rolled back to 112 and used the "--allow-downgrade" flag on the firefox shortcut so I can still load my old profile, but understand this is not a safe option in the long term.

I would like to be able to reset links on a webpage to be as if I have never clicked on them, but I am unable to do so. I have tried:

-Resetting all of the cookies, history, etc for that individual website. -Removing the URLs from the links in question from my browser history. -Downloading this extension: https://addons.mozilla.org/en-US/firefox/addon/remove-visited-link/ and using it -Going into settings and changing the visited link color.

Nothing has worked so far. One thing about the website in question is it has its own unique color for visited links---I am wondering if that is causing this? Additionally, this persists whether or not I am signed in to this website.

Thanks.

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Had a persistent issue where firefox wont display a video inside the bounds of the player For example the attached images show the same video on firefox and opera. opera shows the entire video where as firefox only shows the top left hand corner This has been an issue since the fix for youtube videos having the opposite issue was release Firefox for Android v112.1.0 Android v10

When Firefox updated on my Windows 7 computer, I could no longer access my email on Outlook.com. I had to revert to an earlier restore point on my computer (and thus the previous version of Firefox) to use Outlook.

I very rarely reopen my apps because I also very rarely power off my laptop and use sleep mode instead (usually times between actual shutdowns are around a week). So ubuntu snap likes to update apps regardless of app being closed or not. And once in a while I get my firefox instance closed without me doing it, this would be fine if after reopening it all my tabs were in the same place (or at least I could restore them), but they all gone. I can't restore a session, I only have my history and have to reopen all of them manually.

Please don't tell me to use laptop like a normal person or that I can just listen to ubuntu warnings about updates and close software once in a while. The point is that I don't have this issue with other browsers (also using chrome and brave). If one of this counterparts shuts down unexpectedly it always suggests to restore your session on startup. I know firefox has this feature, but it seems to not work in this exact scenario.

When I go to Google.com, the cursor is in the Firefox browser's address field. And I have to click in the Google search field to start my search - if I remember to do so. Why can't the cursor just be in the Google search field?

I could search in the address field, but I'd have to highlight/delete the address. So it's easier to just click in the Google search field. But I rather just have the cursor be in the search field automatically. Is there a way to get that done? Or is that asking too much?
