Firefox Community Forum

I have downloaded multiple versions of firefox, and when I browse to a site, the response is: MUST ENABLE JAVASCRIPT. I am 81 yo and get confused as to how accomplish this. Please advise!

Hi Mozilla Support,

I made a boo boo, was half asleep trying to shut down and wanted to quickly save a set of browser tabs to come back to later, so "attempted" to create a folder to save within a nested structure in my bookmarks library (using Ctrl+Shift+O editor). I right clicked and intended to hit 'f' for new folder in the structure, hit 'd' instead (delete). This was on an upper level folder structure of thousands (10's of thousands....?) of bookmarks.

Realised my half asleep mistake and doubled down! Hit Ctrl+Z to undo changes.

Well, I guess FF was struggling to process all of the changes, then got confused with the undo, and broke without performing either... F**K. But ok, I will just restore from a backup, I have those setup.

So I went to 'Import/Backup -> Restore, and picked the latest date. Okayed the warning and waited. It failed, gracelessly, by deleting all my bookmarks, then errored. "Unable to process the backup file." Now I can't restore any of the restore files in the list. The latest one looks broken with almost no data, but all of the earlier ones are there, they exist in the folder structure under AppData, say they have 30,000+ bookmarks, and are all around the 20MB size.

None of these restore.

My only hard HTML backup is from early in the year, March, and that is very old in my activity levels.

Also, why are all of the json files failing?

I've since restarted my PC, slept and come back to the problem awake. Still same problems.

I have gone as far as using the 'Refresh' technique in the uninstall options, and despite everything else coming back from scratch, I still cannot restore my json backup files. They all give the same warning, delete any bookmarks I have added and then error with, "Unable to process the backup file."

Is this something that has happened before? I get I screwed something up, but what could be preventing this from restoring? Are all of the json files now poisoned somehow?

Do I have to do a full uninstall and reinstall and try again? And if that fails, what are my options?

I have backups for a reason, this very reason in fact, so that when I error, I don't delete my life...

Would love some guidance on this, if there is a way to check .json integrity, or anything else pertinent I might have missed, I would appreciate a poke in the right direction.

Where I live recently changed to a new timezone and while windows is set to the correct timezone, firefox did not get the memo and timestamps on every website are now an hour behind. I do use a vpn but turning it off or changing locations does not change the timestamps. I have tried restarting the browser and already confirmed privacy.resistFingerprinting is set to false.

How can I change the time in firefox or force firefox to sync to my windows time?

I don't like you last updates with interface changing with curvy bottons and color thems. let me get back .

how may I know which version i had before the  update on november 1  ?

I installed the MOST RECENT version of Firefox and I want to delete it and re instal the version I had prior. I don't know alot about computers so any help would be greatly appreciated. Ray

Hello. I am back again with the same issue that I presented on the forum post three months ago. https://support.mozilla.org/en-US/questions/1594903?utm_campaign=questions-reply The difference is now it is happening on Firefox v157.0.1;everything else is identical. Qubes os R4.3.2 with Firefox 157.0.1 in a Fedora 44 xfce VM. To recap I open one window for Proxmox Datacenter Manager and as soon as I click to sign in Firefox completely disappears. I can open this in Chromium browser and Firefox ESR v.140.17.0 esr perfectly fine. Please consult the original post for all I did to troubleshoot this. I am working with the esr version now but would like to help put this issue to bed. Community members stepped up last time to help me so I am here to do my small part for others. Ask for any info you need and I'll reply ASAP. Thanks in advance. SDS

QuickTabs is acting differently and totally messed up my home page. why can't i move an icon the way i used to? what is meant by the phrase "pinned area" that shows up in the upper left corner when i try to move an icon? are there some new settings that i don't know about yet?

it is not acting the way the attached picture shows. i've also attached a gif that better shows what i mean.

if you can point me to some documentation, i would be grateful.

I've been trying to get the browser toolbox window to work correctly for a couple of days now and I can't figure out what's going on. When I invoke the toolbox window with the shortcut key or through the menu entry the window pops up and asks for permission to connect (I click 'ok' in this box) but the window gets stuck before loading the toolbox ui, screenshot of what I'm seeing is attached.

I'm on windows 11 pro 25h2 and firefox 159.0.

I should note that this is the same behavior in a clean temp profile in firefox, as well as the same behavior in other firefox based browser, such as librewolf.

Does anyone here know what I can do to get this working?

Thanks for any help and let me know if you need any other info.

i turned the machine off last night as normal. turned on this morning and you had signed me out... why? i had all the pages open i needed and everything was normal. i eventually after not getting answers else where signed back in after a typing error.. but i cannot restore last nights session what is or was the problem im back in but something doesnt feel right

Many thanks

Windows 10 desktop, version 159.0, Right clicking on an image used to open the context menu. This suddenly changed. Now, when right clicking on an image, the image itself simply opens in the same tab. Anyone have any idea what happened or how to get the context menu to start opening as normal again?

(Shift + right click opens context menu as normal but never required a shift key hold before.)

I just launched Firefox and was greeted with an advertisement for Firefox. The URL was https://www.firefox.com/en-US/m/friends/

Other than bringing myself back to a different browser, is there a way to block Firefox's own advertisements.

I cant log into f1.com. tried using Chrome and got in. This is getting tiresome.-

There is also a few other things not working, but lets start with this.
