Firefox Support Forum

Hi, I received this error message today-- error: platform version '111.0.1 is not compatible with minVersion >= 111.0 maxVersion <= 111.0

I tried restarting my machine. Same error so I tried to do a refresh of Firefox and I got the same error before the refresh started. So I tried to uninstall and it won't unistall...gets the same error message.

Any ideas? Thanks Amy

Question. How do I restore a profile from windows.old?

Details: Yesterday Windows 10 Failed (yet again , no surprise) Explorer.exe kept locking up and crashing at 1096 threads making it impossible to load/browse anything on my computer. After relogging into the OS I had about 1 minute to do anything before failure happened. (this while windows loads all the bloatware simultaneously which slows down access greatly) In short I could barely load/run mozbackup

Previously every time a windows OS failed I just restored firefox with mozbackup. Apparently that no longer works for firefox and has in fact been out of development for a decade. (tears flowing) The last time this happened ( 3 years ago like clockwork with any windows OS since XP) I moved both the profile folders to their respective locations from windows.old roaming/local to the roaming/mozilla and local mozilla folders respectively.

This no longer works and in fact causes firefox to not function at all. Since I need the passwords locked in firefox to access certain sites like hotmail.com and recover other things for my OS I am screwed. I have no Idea what idiotic concept cause the inability to manually port your profile but I need a workaround asap.

I cannot even log into mozilla.org properly without it either and was forced to use a gmail account just to post this

HELP!!!!

Some how Yahoo jumped in and displayed a yahoo Home page with no way of deleting it. I tried installing Firfox..But it became stuck half way..what should I do to get back to Firefox ?

I recently upgraded from 108.0.2 (64-bit) to 109.01 but it slowed my PC down to the point of uselessness. Nothing else changed application or OS-wise. PC, OS and all Apps are current & up to date. Defrag, Cache Clear a& all similar utilities run on scheduled basis prior to upgrade and everything A-OK.

Is this a Known Issue? If so, is there a fix coming

The download is that I am always movies on the transfer to a good comedy and show us movies because of the news , e-mailed, browser Firefox Android.install and migrate etc

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

This has been going on for a while now, since I want to switch from a certain popular browser to Firefox which I have on another computer, I tried to install Firefox Developer Edition first as I just prefer it and it has some features of which I use sometimes.

However, when I tried to open the browser, it shows a window for like a millisecond then closes. I've also tried with a normal install of Firefox and the same thing happens. I've looked into the Profiles and here is what I've found:

A folder called startupCache (empty) And a file called .startup-incomplete (empty)

Here's what I get when I install dev edition and try to run it:

Two folders, one is dev-edition-default, and the other is dev-edition-default-a very big number

I'll provide a screenshot in this post so you understand all the profile folders.

[https://imgur.com/a/PERMib0 https://imgur.com/a/PERMib0 ] https://imgur.com/a/PERMib0 In dev-edition-default I have the same two files/folders as before, and one more: cache2 which contains the following:

A folder called doomed (empty) And a folder called entries (it has files in it)

In the dev-edition-default-verybignumber I have just startupcache and .startup-incomplete.

If anyone has any idea how to fix neither of my Firefoxes stating up, please let me know!

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

Running Win10 and latest Firefox browser. Trying to get rid of 'Your browser is being managed by your organization' Followed Regedit instructions - only default is listed - no policy. Looked in Mozilla Firefox in Program Files & Program Files (x86) - no policies.json in Distribution. Even did a search in those subfiles - nothing. So how do I get rid of this? I was searching 'Broiling Frigidaire Induction' and one of the videos corrupted my original Firefox. I needed a hard stop to get our of that. I deleted the app and reloaded, and I keep getting the 'Browser managed...' message. Bummer!

I am very unhappy after 2 weeks using the current version of Firefox 109.0.1.8427 on Win 10. Most of my prior add-ons are gone or do not work, even though Firefox shows them as installed.

I can't live with this version; most of my prior add-ons are not accessible (no symbols to click on even though Firefox says they are installed). The others are missing or require me to access the application menu plus several more clicks, instead of single-clicking an icon on the Firefox header.

How can I get back to the prior version (without having to determine and save/restore everything else that changed in my Win 10 sysres since the current Firefox was installed)?

This morning when I exited firefox and then tried to bring it up again (windows10) I got an error message

Error Platform version 118.0.1 is not compatible with

       MinVersion >= 118.0
       MaxVersion >= 118.0

I have a lot of of Important Book Marks and don't have the bookmarks backed up any where.

I don't remember updating Firefox this morning but could have.

How do I fix and at the same time retain my bookmarks an other information from 118.0 I have a different version an older version Firefox installed on my computer (115.0.2) which I only use for google voice - I am using this installation to ask this question.

Thanks,

When I installed version 103 on Windows 10 yesterday, the Tabs, address panel row of icons and the onscreen bookmarks icons doubled in size pushing about half of them off screen. Can I get them back to the size the were?

I keep them on screen to facilitate use and work more effectively. Pushing them off screen reduces the effectiveness of Firefox for me. I spent too much time today trying to find options that would allow me to revert to the former format without uninstalling v.103 - without success.

HELP!!!!

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

Firefox stopped openng, tried to reinstall, no response (see the screenshot) I also use Tor Browser (never any problems) and Chrome (when absolutely necessary, like when Firefox failed to connect to an external email server and for sending queries like this one because Firefox does not work and will not reinstall. )

I reinstalled Firefox, now 119.0.1 64bit on our Mac M2 now OS13.6 via download-reinstall in the owner account on our shared Mac. The "Firefox is being updated by another instance" line in About Firefox still has not gone away after closing and restarting Firefox.

Presuming this will disrupt future updates, I seek help.

Background: Last spring, I upgraded from a 2016 Mac on OS10.15 (which still appears on my Mozilla account) to this M2 OS12 now 13.6. I had previously set Firefox to prompt me for updates because they could disrupt my work on the old Mac. It worked fine up to 118 point something. Up to my ears recently in urgent other stuff, I deferred the prompt for 119. Then, frazzled, I just closed several 119 prompts. Today, after helping my wife use her account on the M2, I found in my Dock's active apps area an icon for something like Updater something-or-other. After a while, I swiped it away.

I upgraded my system from Windows 7 to Windows 10.

Thought Firefox would automatically change from the ESR version to the standard (release?) version but it hasn't.

How do I move to the standard Firefox from ESR?

I have just downloaded firefox from chrome and cannot install it. I have tried the usually uninstall reinstall and restarting my computer but cannot fix it. I have had this issue with other browsers in the past eg opera and brave but gave up on them, however, I really want to switch to firefox so would appreciate your help. For some reason it seems chrome is the only browser I can even open on my laptop (windows 11). Do you know a fix?
