The solution given by cor-el works very well.

Thanks cor-el ! I needed that.

But you won't know it until you access more unique folders than you already have in the list.

For instance, when you access the 8th folder that is different it will be sticky, when you access a 9th that is different it will be sticky. Kind of like a "most recently used" list. You won't see the extras until they happen.

Solution given by Cor-el: There is a pref on the about:config page that defaults to 7 to set the number of entries to show in this list of recently used folders.

- about:config => browser.bookmarks.editDialog.maxRecentFolders = 7

We have enabled the "Prevent changing proxy settings" policy from the Group Policy Management Console. However, we've encountered an issue where Firefox browser overrides this policy. It has come to our attention that Firefox is the only browser that allows users to change the default Windows proxy settings directly from the browser itself.

To address this, we want to prevent users from changing proxy settings via Firefox browser as well. Could you please provide guidance on how to disable this feature?

TL;DR: Make sure you're on the latest... turn Sync off on the computer that isn't showing the remote tabs, then turn Sync back on.

Details:

Three computers (Windows), a phone, and a tablet. Firefox 124.0.1.

Sync is enabled and generally seems to be working fine. But I just noticed, on one computer, that when I went to Firefox View, and clicked on "Tabs from Other Devices", that it was showing nothing, other than the, "Log into your Firefox Profile", which I was already logged in... so that was messed up.

Did a number of things, like checking the other computer, manually syncing from the other computer, coming back to this one, and telling it to manually sync. It also seemed to be stuck in syncing (a grayed button that said "Syncing...")

I looked, and there was an update available to 124.0.2, so I used this opportunity to upgrade.

When I came back in, I still didn't have the remote tabs showing up, so I turned off "Sync" entirely, but didn't log out of my Firefox account, and then turned it back on.

Now I'm seeing the remote tabs.

That's how I fixed it. I hope it helps. I see others having Sync problems, and getting terrible suggestions that are not helpful. In this case it's the simple thing that fixed it for me. Turn it off and turn it on again. If that doesn't work, unplug the computer from the wall and plug it into another outlet.  ;-) ( That's a joke for those of you with a sense of humor. )

I had to delete Firefox on my iPhone because links in emails wouldn't open anymore. Yes, it was set for default.

When I re-installed it, the tabs don't close. I hit the X to make a webpage go away and open a new tab. Hit that X when I'm through. Then close an empty Firefox on my phone.

When I reopen Firefox, I get all these little miniature webpages of the tabs I closed. I don't want them. I closed them because I was through. You guys are wasting my time making me close them again and again ...

Please tell me how to set Firefox on my iPhone so that when I open it I get my homepage with shortcuts I have chosen and nothing else.

Thank you, Roxanne

Does Mozilla Firefox for Android have plug-ins?

When I open Firefox, the tabs from the previous session do not open despite the setting. I end up with a start page showing only a new tab page. This has been happening over the past few days and I don't know why.

Does anyone have any ideas why this is happening.

HP laptop isn't recognizing the wireless printer. I go through all the steps but when the screen usually shows the printer name and info. it fails to do this. Can't get any farther than this.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

My windows got corrupted had to reinstall everything and this means i have lost my old Firefox account password is there anyway i can get all those saved passwords as i need them. Any help would be great

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee

I am trying to use a new HP Spectre laptop which will be my all purpose home computer. I selected Firefox Browser as the default browser but I don't believe it has ever come up as my browser. It is loaded among many other apps (?). I used to call them programs (?). I get Edge, Chrome, Bing, and others, none of which I want or ask for. They just seem to appear randomly.

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.
