I am disabled and cannot type, and colleges 100% online this year because of CovId 19. When I tried to download the add-on for Dragon naturally speaking the program I use to write Foxfire says that it appears to be corrupted and will not allow me to download it. I know it's not corrupted because I have downloaded it from the same site for chrome. Can anybody tell me how to get around this problem? My sincerest thanks Kevin Arthur Cleveland

I was trying to switch between channels by changing the value in prefs.js

I guess some of the paths are not fully supported. Like from nightly into release it is downloading and restarting the browser but update fails and starts all over again leading to a vicious infinite loop.

I was googling fine, went to eat, and when I came back this security alert appeared when tried to google something, and it also appears if I try to enter Youtube, like if Google sites now are a security risk for Firefox?

Edge opens them, Chrome opens them, WTF?? I just went to eat, didn't update nothing, didn't add a cookie, didn't restart the computer, I didn't even close the browser, I JUST WENT TO EAT. This is for those that say "restart", "clean your cookies", "update Firefox", I've already tried the obvious, what the hell happened? Did Firefox get in a fight with Google or what?

Do developers read these topics or we're just "helping each other"? Well, thanks for any info on the matter...

Hello, I see that when adding a new bookmark, Firefox now remembers the last used location and sets it by default. I would prefer to keep the previous behaviour of defaulting to "Other bookmarks". Is there a way to disable it please?

Thank you

For some reason today all of the sudden I can no longer see YouTube videos whether they are on the YouTube site, or embedded on another site. I checked another browser, and there is not issue there (Microsoft Edge). I then tried to sign up for YouTube, but the process broke down because the confirmation code was never sent to my e-mail. I also turned the AdBlock off, but that didn't help either. I checked with my ISP and there are no issues on their end. Everything else I use is not affected by this issue. So what gives?

Dear All I switched over to latest version Firefox, installed it on other, parallel drive (D). However, older version FF -still on (C)- updated itself. (Left it there because I wanted access to some data while changing - bad idea, obviously!) Now there's a (new) version on either drives. Can I remove (C) version? C-disk is rather small, therefore idea came of swapping it to (D) And HOW do I remove it from (C)? Many thanks for any idea All (MY real name)

hey i have firefox 8.5 - and a problem since v8.4 and present. Web pages load very slowly - the whole browser is very slow, the load on the frame RAM and CPU is reaching its zenith with the windows open. In one word the browser has become useless. Anticipating responses - 1. In safe mode - browser speeds up slightly, but websites still have lags and take a long time to load. 2. I reinstalled firefox - the errors continued. 3. I turned on firefox without logging in and with add-ons disabled - the browser worked with the errors described above. 4. I turned on firefox and logged into the profile, but turned off the add-ons - firefox - still has errors; I turned on a generation of additions (recommended) - firefox still has bugs. 5. My antivirus is not blacklisted by firefox - and I have no worms etc. 6. Standard or changed settings - firefox doesn't work well. Any suggestions or advice? Websites like FB, YT and others are simply unloadable with such lags. thanks.

I prefer to save my bookmarks to my Bookmarks Toolbar but FF defaults to Other Bookmarks. It's annoying at best and a waste of time to have to select the location I want every time. This should be an option. I don't want Other Bookmarks in my toolbar, either, thanks very much.

Dell XPS 8930, Solid-state C drive and 1 TB D hard-drive, Windows 10 - updates current, Firefox recently updated to 85.0.

Since the update to 85.0 operations in some areas are different, but I was able to restore actions back to how I preferred.

One action causing me grief I haven't been able to resolve is actions involving pdf files attached to an email. I left-click on the attachment download arrow and choices are presented (normal).

If I select "open with Adobe Acrobat" a box appears stating "There was an error opening this document. This file is already open or in use by another application" (I didn't open it and I didn't initiate another App) and the file doesn't open.

If I choose "Open with Firefox" a window opens with "file:///C:/Users/metzg/AppData/Local/Temp/Invoice-1.pdf" in the Address bar, but nothing else happens. If I click the address and click on the address that appears below with " - Visit" added to it the file opens successfully.

If I choose "Download" the pdf file appears in the Download location and will then open normally.

I prefer most often to just open the pdf file directly in Adobe Acrobat and save, print, or take another action of my choice. Since the update to 85.0 this problem has been an issue. I have searched Firefox help and haven't found solutions that specifically address this issue. I have tried changing the settings in options, closing Firefox, opening Firefox and changing back to "Always Ask" and the issue persists.

If someone else has experienced and resolved this issue I would appreciate info on how you accomplished a solution!

I am new to firefox. I created a firefox account in firefox browser in Windows first, and imported bookmarks, etc., from my chrome browser. Next I installed firefox in my Ubuntu OS, and it worked fine, the account can be logged-on and everything was synced.

I get the problem when I install firefox on my Mac. I installed the same firefox browser version as I installed on my Windows, except that it was for the Mac. I tried to log-on with the account before, but it asked me to create a new account, even if I use the same email address to register my firefox account before on Windows. So, do firefox use the same account on Windows and Mac? Is there a fix to this problem?

Hi all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

Thanks & greetings Markus Fehn

Hi I am encountering a strange issue. I have two firefox computers and syncing is active.

I am trying to restore a previous version of my bookmarks (using the bookmarks library, Import and backup menu, restore function). My problem is that at one of the following sync (ie within usually a couple of hours max) the previous set of bookmarks is systematically restored by sync.

I have un-registered / re-registered both computers, tried to use a different backups (from recent history or from a file export), tried to run sync immediately after the restore... nothing helps.

I activated log on success for sync. Apparently the restore is just ignored as I get this: Sync.Engine.Bookmarks.BookmarkSyncUtils DEBUG pushChanges: Processed change records: {"weak":0,"skipped":0,"updated":0} and later, suddenly the browser realises that lots of bookmarks are missing and cancels all the changes: " Sync.Engine.Bookmarks.BookmarkSyncUtils DEBUG pushChanges: Processed change records: {"weak":0,"skipped":0,"updated":4764} "

Has anyone faced the same issue? Is there a way to force a unidirectional push from the browser to the server? Thanks

PS: FF 85, one on Win10 and the other on MacOS Big Sur. Same behaviour on both machines. PPS: The machines are in two different locations. It is impossible for me to force the change simultaneously on both computers.

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

I am unable to edit videos I upload to YouTube in Firefox. Whenever I try to save, the page greys out and nothing happens. When I'm about the leave the page, I'm warned it will discard my changes. I've already tried disabling add-ons and tracking protection, but nothing. I can only edit videos when I'm uploading.
