Firefox Support Forum

Mozilla account in Firefox PC browser always asks to re-login every 1 day. This problem appeared after updating Firefox from version 119 to 120 and 121.

As in the image below, "Account Disconnected" and a triangular warning appears in the Firefox menu bar. I can't access any sync data like passwords, bookmarks, plugins if I don't re-login.

I only use this mozilla account on 1 PC.

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

When I open a locally downloaded pdf in firefox, the background is displayed as what was previously displayed on that portion of the screen, and scrolling simply overlays moved text over what was previously displayed. Does not appear in screenshots. One of the images shows what the pdf looks like prior to scrolling, and one after.

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

I've noticed lately that my Firefox keeps freezing and hanging up at random periods for no apparent reason. I have very few plugins and it even happens with them all disabled and removed. I've tried resetting Firefox to default everything yet it makes no difference.

Also I can not clear history. I've tried multiple different clear history plugins but none of them work at all. And when I try the traditional way of clearing Firefox history the window pops up and then the entire browser just freezes while 'clearing' and never gives me back control, I have to force quit and restart to regain control. And then when I relaunch the history is still not cleared!

So aside from the constant lagging and lockups it seems that any attempt to delete history whether using the inbuilt function or adding plugins messes up the whole browser.

Googling this issue it seems others are having the exact same problem with Firefox and yet any suggested solutions (reset browser) don't seem to be working for may of them.. Or me.

Every third or fourth website I open, I get the "Hmm. We’re having trouble finding that site." error. if I wait a few seconds and hit try again, it works. Very frustrating and slows me down every day. Here is what I tried so far:

-Booted firefox in safe mode to make sure it is not any of my extensions. (This did not solve the issue) -Cleared cache time range "everything" (This did not solve the issue) -Made sure my version of firefox is up to date -Updated windows and restarted my computer

Some clues that may help you help me: -This issue only appears on my home PC but not my work PC or laptop -The websites I am opening work fine on other browsers.

Please help! I am getting tired of this

I'm having problems with Firefox using 75% of processor capacity. In "top" I see many instances of "Isolated Web Co".

At the moment of this screen shot the processor is not overwhelmed, however, it will sometime jump up to 75% and the system will seem to freeze.

What is the "Isolated Web Co"? I'm thinking a virus.

Thank you.

Hi, I have a problem starting yesterday. When I video chat with anyone using Firefox on FB messenger they can see me but I cannot see them. Only a black screen where they should be showing. I have tried everything from uninstalling to different settings. I have made sure also that permissions were set correctly. Also it has been giving the error "slowing page down" or what says. Nothing helps. Now if I use Edge or phone it works just fine and we can see each other. This has never happened before. Also, the messenger games wont work on firefox either, but will on others. Please help if possible or tell me how.

Thank you

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

I've always used Firefox browser instead of Microsoft Edge, and I would like to continue using Firefox. However, it will not run in its current form under Windows 11. Does Mozilla plan to keep it compatible with Windows? I would like to keep using Firefox.

I don't need any images, you know the problems ... Freezes, no internet access.

A while ago I formatted my computer, and installed FireFox for the first time. Ever since installing FireFox, I noticed an issue which has been a constant source of frustration, when I rewind any YouTube video the playback volume changes to a lower value, until I rewind again.

I tried looking online, this is the closest match I've found, but there's no solution there

I tested this issue on different browsers (Edge, and IE), no problems there. I tried disabling extensions, no change. I tried resetting FireFox, no change. I made sure that Windows doesn't automatically adjust system volume. I tested this issue on different Video platforms, no problems there.

I use YouTube when I practice (music), so I rewind a lot.

Any help is very appreciated.

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

Please help me remove this blank area section on the web pages. its on all of them on every tab. I have tried restarting and updating. I cant get it to go away.

thank you Mark

On Microsoft Edge, whenever i type the first letter of a word it will suggest automatically the recent words that i have use. How to enable it on Firefox, i already browse the settings? I really need it on my job specially doing reports. We can only use Firefox to access our websites.

Maybe this is a bug report?

Adobe Digital Editions software is used by Archive.org, Open Library, Kobo store, and many other entities to deliver DRM-ed material in the form of .ascm files all named the same "URLLink.acsm" In the past, the download dialog box asked if you wanted to open the file in Adobe Digital Editions or save it to a location.

After the latest update today March 11, Firefox does not allow you to open the files in Digital Editions. It goes directly to "Save to" download location. This is not how the .acsm files are supposed to be handles. They all have the same name and are supposed to be opened into Adobe Digital Editions directly.

In Firefox Settings there is a box for - "Applications

Choose how Firefox handles the files you download from the web or the applications you use while browsing."

However, .acsm files do not appear and typing ".acsm" or the filetype name "Adobe Content Server Message" yields nothing inside this box so I cannot get Firefox to open these files with Adobe Digital Editions.

This is beyond annoying. These files are meant to be opened straight by Adobe Digital Editions. I tested it on Chrome and Chrome lets you open them fine.

Either the "Applications Choose how Firefox handles the files you download from the web or the applications you use while browsing." box functionality needs to be fixed to recognize .acsm filetypes or the previous default functionality of allowing me to choose "Open with Adobe Digital Editions" or "Save to" for this filetype needs to be restored.

If there is some other way to get this functionality back in the most current Firefox version, please advise.

Thanks!
