Firefox Support Forum

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

I recently switched from windows to Linux, and was using it for 3 months now. It was due to window recall Feature. But still i was using chrome as default and daily browser. I wanted to explore firefox, its great actually, except 2 things which might need me to switch back to chrome or brave.

1. it don't have fu**king Profile switch, I mean i use 11 Profiles On Chrome, most people still use 2-4 profiles, how can we move to a browser that dont support profiles. I know we can add profiles by "about:Profiles" I tried it. It worked but guess what? To switch profile i have to manually go to that page to launch it. So much time consuming and frustrating. Why not simply add a btn on profile pic like chrome to switch profiles?

2. Add-ons is good thing, but there should be a way to install things from chrome web store, i not found any.

If firefox can fix these two things firefox can simply grow back to 30+ % market share, but if not people will just test l;like me and go.

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

OK, I have Firefox (Windows 10 AMD64, desktop) configured to delete history when I close it.

So, I see that regular webiste cookies are deleted.

But are the HSTS website "super cookies" deleted?

https://ipleak.com/articles/what-is-hsts-super-cookies What are HSTS Super cookies and why are they dangerous?

thanx.

why do i get a message that firefox has crashed. what has happened. i am not satified with firefox. it is very slow and sometimes crashes.

but the main question is: what can i do right now.

A friend informs me that Firefox settings > General > Browsing > Always show scrollbars has been removed in version 129.

This is alarming because I need that option for accessibility reasons.

Could you please check and, if necessary, reinstate this vital option?

Thank you!

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

When I used to take screenshots, they would be automatically named with the date, time, and part of the text captured regardless of language. A few days ago and with no reason I can discern, it now saves any non-English screenshots with something like this "Screenshot 2024-06-23 a[...].png" instead of "Screenshot 2024-06-22 at 08-02-28 Politics Policy Polit[...].png" (usual for English text and what I used to get with all languages).

Which means I have to manually rename screenshots. Does anyone know how I can fix this because I am working on a project with lots of screenshots for topics from different languages?

I just noticed today that none of my various folders storing important bookmarks work anymore and they have all lost their own indiviual logos. Instead there are just globe logos!? This is very recent so i can only imagine so kind of update has done this?

Can i get these fixed?

I recently suffered from the "127.0.1" not compatible error. Eventually I was persuaded to reinstall firefox from the Mozilla oficial site using Edge, despite having reservations about losing my passwords etc. which has happened before. Fortunately, the installation routine included an update option which preserved all of that. However, my menus bar (File ...... History, Bookmarks...) is missing and I cannot find any way to get it back. I rely upon it to restore previous sessions, because I routinely have the same 7 tabs open and want to be able to get them back after an update or laptop shutdown, and also use it to search history and find bookmarks that are not in the bookmarks bar. Any help welcome.

As an asside, my pet hate is updates to any application that remove, move, or hide a very useful feature without explanation or warning and claim to be to "improve the user experience". Take it from a long standing user, they don't. Quite the contrary.

For two days will tab crash for TikTok. For years, will not allow access to certain sites and no contest entries for the last few months. Worked before. No phone help and to download the browser doesn't work. I was upset as won't load TIktok and I NEED IT as use it daily. Please fix it ASAP!! I wasted time contacting Monzilla, as was only link for Firefox. They told me no help wasted today.

Hi folks,

I'd like to obtain some clarity on provenance aspects of Firefox released as a Flatpak.

I see in this article that one of the options is to use flatpak package: https://support.mozilla.org/en-US/kb/install-firefox-linux

Is this article produced / reviewed by mozilla? Is flatpak an officially trusted, backed by mozilla, means of installing firefox on a system?

On flathub one can observe the "Verified" seal which indicates that such package is developed and maintained by original package developers (in case Mozilla). One can also observe in multiple forums here and there that mozilla is the one that builds and maintain this package.

Though a seal is nice, and users opinions are ok, it would be good to have artifacts that would evidence better this relationship. Also, would be good to have this officially stated in mozilla's website, under "Download options and other languages" section, something like "you can also safely install firefox through the flatpak package available on flathub which is developed / maintained / signed by mozilla itself".

Or maybe all of this information is around and i am just not able to link it together.

Thanks

There is an issue with 3 extensions: 1. Briskine. 2. Simple Gmail notes. 3. Boomerang. This issue is taking place only when Briskine is active and only on Firefox.

When Briskine is active Simple Gmail notes does not display at all. Boomerang does not display correctly so there is no access to the full screen and options.

This only happens with Firefox, not with Chrome or Edge. Also, it is a know issue that's been going on for a while. I wish it could be fixed. Thank you Adam [removed phone# and email from public support forum]

Every time I open Firefox I get 3 pop up windows. 1. System is infected! Click here to scan and clean. Via.qowin.co.in 2. McAfee: System Alert! Click here to fix the error Via.qowin.co.in 3.McAfee: ZEUS.2020 Trojan detected Click here to delete the virus Via.qowin.co.in

I deleted McAfee. I cleared the cache. When Firefox opens it opens to qowin.co.in

How do I fix this?

how are shortcuts created on my "new tab" home page in firefox browser. I used to be able to create the shortcuts I wanted, not random shortcuts that I might have visited once. Now shortcuts appear that I don't want. I know I can remove them by dismissing them but I should not get them in the first place. Please help.

When im starting my computer, suddenly this program with old firefox logo auto starting on windows taskbar, i cant open(maximize) it....when i hover to that old firefox logo, it just shows random text......

If i'm opening task manager, that program or something is in C:\Program Files (x86)\Common Files\AlphaPress under the name update.exe.....i alrd close that program, delete that, and running malwarebytes, but didnt find any threat.....If u can reassure me that it wasnt dangerous malware or anything....maybe some real firefox update?
