Firefox Support Forum

I currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.

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,

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!

Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

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

I get no warning when auto updates begin installation. I get notified about 1/2 way through the process. The pc (Win 10 pro 64bit) slows to a crawl for 5-10 minutes, then the install finishes, & then it's another 5-10 minutes before the pc is usable.

I would really appreciate a "update is available" notification, which I would agree to at a convenient time. This is really getting to be problematic. Other browsers that do auto updates don't hose my pc.

Thank you!

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

I cannot use, update, uninstall, refresh, or reinstall Firefox (and haven't for four or more years). I always get this message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." But I have (obviously) shut down the computer entirely any number of times in all those years. What can I do? I will be taking college classes and Firefox is one of the few browsers that the college supports.

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

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

Windows 10, Firefox will not load URLs or settings page. Uninstalled Firefox and downloaded a new copy. Upon install system error message attached appeared but browser appeared with all my bookmarks and loading error message (attached with bookmarks erased). New pages will not load.

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

I installed Firefox on Windows 10, and when Firefox is running, the taskbar is blank with no icons. I just installed Firefox, logged into my Firefox account, and did nothing else.

Hi! I have latest version of Firefox installed on my PC. But sometimes I am programming for web. So I would like to have Firefox Developer Edition as well. But I don't want them both at the same time - one for my usual web surfing and another one for web programming using leading (or even bleeding) edge features.

How do I install and use them separately? I tried running Firefox Dev Edition installer, but it does not ask questions like where to install and which Firefox profile to use.

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)?

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

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. )
