Firefox Community Forum

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

I want to re-order the add-ons / extensions in the toolbar shared with the search bar. Customize toolbar only has functions/icons related to the operation of Firefox. I want to customize the extensions toolbar, but how?

In the add-ons page, I can remove, disable, or enable extensions, but I cannot change the order of them.

As an example, there is an add-on for my Firefox account that is leftmost in the bar of extension icons. I would like to move it all the way to the right. Again, how would I do that?

Thanks for your help.

Hello, since 2 weeks I have some plugin who are not displaying in my wordpress dashboard and they are working normally on Chrome. This morning I got this message: An error occurred while connecting to WordPress REST API. It seems blocked by one of your plugins or your theme. Thanks for your help

Hi there,

I'm trying to add multi-containers add on to a new Firefox install, it installs, but the icon doesnt show up. It's not hidden in the customise toolbar menu either. Have tried removing/re-adding, but it doesnt come up. It is possible to get to it by clicking the extensions icon, then clicking multi-container, but this isnt very user friendly. Is there a way to resolve this?

Thanks!

I'm trying to move to Firefox from Microsoft Edge on Linux. When I go to import data from another browser Edge is not an option. I have a CSV file that I exported from Edge. How can I import this CSV file? I found something on reddit that said to change security.allow_eval_in_parent_process to true, but that no longer works. How can I get my passwords imported without having to install another browser and import to that and then import to firefox?

I am trying to make the address bar thinner (reduce the height), but after trying all the recommendations on the Internet, I did not succeed. I did this through the userChrome.css file and by minimizing the icons. Please help.

My search engine page when I click on FF changed to Bing this morning. I installed Avast Virus Remover yesterday, and nothing else. All methods given on all the answer pages did not work (do not find the link) or I do not know how to get to the command (e.g. Tools - xxxx - xxx - which tools?) I can't open FF so I can't use any of its options, unless there is a way to open FF without this Bing thing.

Win 10. I ran all the AV's and malware programs and they found nothing because I really do not surf a lot. I can't say which version of FF because I can't open FF

Thanks

i would like to set it so that when i put my mouse on the top of the full screen, it doesnt exit full screen. when i hover my mouse at the top, the browser tabs appear. i need to stay in full screen. please is there a setting to stop this from happening? is there a setting to make the full screen stay on until i use my keyboard?

(context: i play a browser game, agar.io, in full screen, and when im trying to go up my cursor is no longer in the game and i temporarily lose control when that bar appears. also the game window distractingly resizes itself to fit the bar. i just transferred from opera and i dont want to have to get used to this happening, even if maybe for someone who doesnt game its useful)

I am perpetually annoyed by Firefox's tab hotkeys. Meant to type "^" when writing an equation? Well, too bad, you accidentally pressed ctrl instead of shift, you are now on the 6th tab of your whole browser, and you gotta go find the tab you were on. The ctrl+page up/down hotkeys are slightly less annoying, although still very infuriating. Is there any way to disable this behavior?

Cannot access website. Getting Error code: SEC_ERROR_REVOKED_CERTIFICATE. Website owners say certificate is valid and can access on other browsers. Why is FireFox blocking access to site?

I am using the latest version of Firefox (112.02 32-bit) with Windows 10 but am being blocked from certain websites by the Cloudflare security app because it says that my browser is out-of-date. This was particularly embarassing when I was trying to buy tickets for a concert recently and was unable to access the venue's online payment system.

It may be that Cloudflare is confused because I occasionly use an older version of Firefox (52.9.0 32-bit) with an earlier version of Windows. How can this issue be resolved so that Cloudflare does not block legimate access to websites when I am using the most up-to-date version of Firefox?

My credit union (my only checking/savings account) blocks one page even though I have the pup-up setting set to "always allow." How can I correct this?

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

I was in italy when I first created my firefox account and by default it choose italian as language. All of my search results are in italian even though in browser settings I choose English as preffered language. Now I discovered that actually my firefox profile is in italian that's why I see results in italian. In the profile settings (https://accounts.firefox.com/settings), there is no option to change the language. Please help.

I just hooked up a new Windows 11 computer and installed Firefox, which has been my default browser for many years. I was irritated to discover after I synced with another computer that almost all the icons for my add-ons have disappeared with no apparent way to get them back. I NEED some of those icons and it makes absolutely no sense to have them gone. Before anyone suggests it I have checked where you customize the toolbar and none of them are there. I refreshed Firefox just in case it helped and of course it didn't. Checking online only results in finding other people with the same problem with no helpful answer. It's almost like Firefox is begging people to leave and go to another browser, which I probably would since I'm so irritated at this issue, but I'm not happy with any other browser. Firefox is the only one I've remotely been happy with, but the way it is right now I'll be pretty much unable to use Firefox on my new computer. At least I still have my icons on my Windows 10 laptop until I'm forced to upgrade to 11 but my new desktop just might end up Firefoxless unless I get a helpful answer.

How do I clear Cookies and other junk from Firefox please? Sorry I am clueless with all this technology, a technosaur. I am 73 yrs old, never studied computers, maybe one day I'll find time, between fighting other battles with baddies...

Hi lovely People, I try to setup 2FA on accounts.firefox.com with Authy on Android. In Step 1 the code generated from Authy is accepted.

But then, in step 3, when I try to paste in the just in step 2 provided backup activation code, it tells me it's wrong. Am I stupid? I just copied that key from step 2 ... I tried it many times now. Checked if my clipboard is working as expected, tried to delete the spaces in between... I used FF Standard and FF Developer Edition. My Authy is working elsewhere.

Any help? I searched the Forum, found some relating questions, but they never get answered. No one having the same issue?
