I currently have a Windows 7 PC with Firefox version 112.0.2 and normally use the EXE files from Mozilla's FTP site (ftp.mozilla.org/pub/firefox/releases) to upgrade Firefox.

With Mozilla's decision to move Windows 7 users on to the ESR branch of Firefox I was looking for the best way to install the ESR version using EXE/MSI files. In this regard I have the following questions:

1) Is it best to first install the standard Firefox 115.0.3 EXE (last standard Firefox for Windows 7 users) and then the 115.1.0 EXE (first Windows 7 ESR Firefox)?

2) Would doing the above method cause any conflictions?

3) I read a while ago that the ESR version is a separate install that can run in parallel to the standard version, if this is true would it be ok to uninstall the standard version after the ESR install to not leave vulnerable versions on the system?

4) As the latest ESR version is 115.5.0, if the above method is ok. After installing the standard 115.0.3 should I still install 115.1.0 ESR or move straight to 115.5.0 ESR?

5) When moved onto the ESR branch can you jump versions or do the updates have to be installed in order?

After selecting Mozilla as my default browser, I tried to perform a search but the only page that loads is the page that wants you to download Mozilla on desktop and android, which I already have. Each time I've tried to do a search with Firefox this is the page that appears, no search results of any kind, but when I switch my search to duckduckgo and perform the search I get results. Can someone please help me understand why I can't perform a search using firefox?? Thank you in advance for your help!

My Simple Tab Groups disappeared after one of the recent Firefox updates. This has happened before. Now, after considerable time rebuilding my simple tab groups, when I get a notification that a new version of Firefox is available, I dismiss it. I am afraid of losing them again.

Have you heard this before? Has the issue been addressed? Is it fixed? Is it safe to update without losing the tab groups? Is there a way to back them up and restore them later if they crash?

I recently updated to FF 119.0.1. I am finding that URL completion in the address bar is kind of random. In FF 118 and earlier, URLs were completed predictably, and it was pretty clear that they were based on a) bookmarks and b) frequency of use. Now, it seems like the frequency info is lost every time I restart FF. In that case, I might expect that the URL offered would be from the oldest bookmark or maybe the first in alphabetical order or something predictable, but it isn't. It seems to me to be random, and it is very annoying.

Is this a new bug, or is there perhaps a new setting that I can change to stop the madness?

For relevant settings, I have:

 - Provide search suggestion: checked
 - When using address bar, suggest: browsing history and bookmarks are checked, nothing else
 - I'm using Custom History settings: Remember browsing and download history is checked, Clear history when Firefox closes is checked. 

I have used these settings for years in previous versions of FF, and there hasn't been a problem until now.

Thanks!

We are currently attempting to automate our Firefox update processes. Currently we use robocopy to push out new versions on release, but ideally we'd like to use the background updater instead. We are currently on 64-bit 119.0.1, on Windows 10 Pro 22H2. We'd prefer not to switch over to ESR if at all possible. I've already reactivated the AppAutoUpdate and BackgroundAppUpdate policies, and DisableAppUpdate is disabled, but I'm still being hit with a UAC Admin prompt when I try to launch Firefox. I tried to bypass it through the registry at [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers], with "C:\Program Files\Mozilla Firefox\firefox.exe" = "RUNASINVOKER", but that also doesn't seem to have done anything. Any and all assistance would be appreciated

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

When I have to change a setting on my LAN printer, an HP, I should be able to access its built-in settings module. Firefox will not let me access the printer because it doesn't have a trusted certificate.

So I get a blank page with the message: "we could not verify the certificate: reason = untrusted" and doesn't give me any options. In versions past, I recall an option to connect anyway if I trusted the site.

If there is a setting that lets me enable the option to continue anyway, where is it? Alternately, is there an exception list, perhaps by IP address, that will allow the browser to connect? Perhaps another solution?

I can't be the only one who is encountering this issue.

Thanks,

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Firefox seems to be hanging up my computer every once and awhile. Why I think FF, if I am able to kill it with task manager- all is well. Prior to that system is pretrty much locked up, sometimes can't even get task manager running. Also, about twice a week I get a message from FF about oops your Foxnews tab has stopped., please send report. I haven't sent report, just do a reload.

I have run 3 virus checkers, chkdsk and sfc /scannow and all are okay no virus, disk or system files missing.

Thinking of switching browsers for awhile?? Then seems there is a place in profile that has passwords, but I forgot where. Maybe I could download a completely new copy of firefox and keep my profile?? Then again maybe my profile is messed up.

Any suggestions the best way to get a completely new copy of FF??

On Windows 10 current release and now FF 119.0. Down to using Flagfox, Malwarebytes Browser Guard, tab reloader, undo close tab, web threat shield (webroot). Was for years using Noscripts, but stopped it for the last few weeks. Actually I stopped Malwarebytes Browser Guard, web threat shield and noscripts and still got hung up. That only left Flagfox, undo close tab and tab reload running as addons.
