Firefox Support Forum

When I try to open a file from a particular site, a .csv file, Firefox seems to think it's a txt file, as seen in the attached image. When I save the file it downloads fine as a .csv, as it should. Why is it that this .csv is seen as a .txt only when selecting "open" but not "save" and how can I fix this? Thank you.

I can't find an answer to this Q: Updating to Windows 11 will Firefox retain & install w/my current bookmarks or should I plan on saving and reinstalling them after the update? Thx for your help!

I need to download Firefox ESR version 78.11.0 in order to access some other software which only works on that Firefox version. However, when I go to https://support.mozilla.org/en-US/kb/switch-to-firefox-extended-support-release-esr#firefox:win10:fx91, open the drown on the right and select the 78-version, click download, it still just downloads the 91-version. What am I doing wrong?? Have tried doing it with Edge and regular Firefox latest version but without success.

W10 Pro (sys info & TS info are below) I run both w/32-bit 91.4.1 esr & 64-bit 95.0.2 on the same machine. I tried to manually upgrade the esr to 64-bit but am told 'unable - system incompatible' and get the W XP & Vista support ended at 52.9...I'm running 32-bit 91.4 AND 64-bit . Help me understand if/what is incompatible so I can manually push my esr to 64-bit. Getting to 64-bit from 32 (per help page) says to just download and run the 64-bit ESR setup.exe. That fails...same issue...incompatible. FF setup thinks my OS isn't W10 Pro....so does the ESR FF 'application menu'...and the TS info. My ESR is set as the default browser app. AND I don't have any (known) issue with the 64-bit 95.0.2 Advice? Do I need to uninstall the 32-bit esr strangely I am already running 91.4.1 32-bit esr...says HELP/about.??? I'd like to know what esr is actually running...I presume 32-bit. Thx, wgk

I'm trying to move my profile from an "old" laptop to a "new" laptop. I've copied the profile and put the files under a new profile which I generated with the profile manager on the "new" laptop. When I try to start firefox on the "new" laptop I get the Error Message "... your using old version ... this might corrupt your current data ... please create new profile" When I create a new profile (see above) I'm in a circle (catch 22 ;-))) When I click "close" no firefox opens.

"old" laptop runs Version 94.0.1 "new" laptop runs Version 93.0

I started Firefox and it has lost everything I had - my bookmarks, history my wallet - gone. How do I restore? I am stuffed if I can't go back to what I had yesterday

Hello. I am having download problems. Every time I download a file the download speed in kb/s freezes and the download does not progress although there is no indication that the dl is paused. The only solution that works is for me to click pause and then click continue multiple times for the dl to continue. Is there anything I can do for this to work? I already reinstalled firefox but it still does not work.

Whenever I try to download something off my google drive, text pops up in the bottom left corner, but then nothing happens. It works just fine on microsoft edge, so I think its a firefox issue and not a google drive issue. I tried refreshing my browser, deleting my cookies, updating my browser, turning off enhanced tracking protection, and anything else I could think of. Please help.

I get it- there's a new update. I saw the message. THREE TIMES today already I've been subjected to this message. I've spent the last week going to about"config disabling EVERYTHING, desperately trying to stop this patronising Big Brother subjection. Is THAT what Firefox wants? I'm on a work laptop- I can't alter files. I'm not going to update after 57 summarily removed ALL my addons. If I can't remove this constant nagging, I'm giving up completely and moving to Bravo. The fact there is no communication with Firefox reps and it subjects users to nagging shows how unreliable and dishonest it's become.

Hello, I am migrating profiles from a Time Machine backup of my mid-2012 Mac, which was running Yosemite, with Firefox 70-something, to my new M1 Mac, which is running Monterey, with Firefox 95.

I read an article which said I should copy ALL of the files inside my old profiles folder to the new folder and replace the new files. I did this, and my bookmarks and passwords showed up. However, now the type is about 1 pt. in size and everything within my window only reaches about half the width across.

I think what happened is that I copied over a file that deals with the size and display of text vs. resolution that was set for the old Mac.

My questions are: 1) What might the name of that profile file be? 2) Am I able to delete just that one file and things will display correctly? Or, 3) Do I need to do a re-install of version 95 and then only copy over bookmarks and password files?

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

Since "upgrading" to 95.0.2 firefox crashes frequently, and website, particularly game sites, stutter, repeat, and crash. Please tell me how I can go back to a working version. This unreliable version is just too frustratingly Microsoft for my mental health.

I am using El Capitan because I am using an old Mac. Operating system 10.11.6. I've tried downloading FESR but always get the same error (pictured). What is the problem?
