A few days back, the browser "+" symbol used to open another tab at the top right of the browser window disappeared like a bad odor in the wind. Performed a search and located instructions on line that explained using 'about:config' settings to restore the symbol. It worked and I was browsing wonderfully again.

After closing the browser a few days later, the + symbol has vanished again upon restarting. Have searched in vain online to locate the parameter in about:config that I need to reset, but cannot locate it and I do not remember the parameter to search. CRS problem.

I can go into the Customize menu and drag a folder with a + symbol to the menu bar but it behaves differently. Just want the convenience of clicking the + symbol to automagically start another tab.

Every time I try to access Citbank to view my account I get a screen that says "Failed Connection". How can I stop this? This is "CITBANK" not Citibank. Thank you for your time.

Hi

i use Mozilla at work, in logistics.

When booking shippments we use "nShift". Booking is repetitive, so the autofill function (in swedish its autofyll) is pretty useful, and we have used it extensively...now for some reason it has just disappeared and we cant get back.

See uppploaded imgage, tried to follow the instructions,..... also in my edition there is no subheading caled "Formulär & autofyll", it just says "Autofyll".

So the question is, what to do to get the autofill back.

Thnaks for all the help i can get.

I'm having trouble installing Norton Password Manager, I keep getting a corrupt file, won't install, so I am running through the checklist of possible fixes.

The one I am up to is this :-

Refresh Firefox Click the menu button (≡). Select Help, then choose More troubleshooting information. Click the Refresh Firefox… button on the right side of the page. In the confirmation window that appears, click Refresh Firefox. Firefox will close and restart. When it finishes, a window will show the data that was imported. Click Finish. Choose whether to restore your previous windows and tabs, then click Let’s go!.

I cannot find the "Refresh"

I've run Troubleshoot Mode

I have cleared the startup cache, problem not fixed.

My bookmarks, history and passwords have disappeared. I looked at the articles, refreshed firefox, have restarted firefox and my computer multiple times but cannot retrieve them.

This is the message when I start firefox

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

Even though I have settings set to load previous tabs when Firefox is started up but when it is restarted it doesn't load the tabs. This has only occurred the last few days. My solution is to select "reopen all windows" which does what I want but also opens several other versions of Firefox. Noteworthy, confusing, but probably not associated: In the course of trying to work through this, I have had a baseball playing on Chrome. I ended up closing out Chrome but the baseball game audio continues even though the Chrome appears to be closed on the taskbar.

Hi everyone,

I’ve noticed that Firefox tends to use a lot of memory when I run several browser-based tools at once — especially web calculators or dashboards that update data dynamically.

For example, when I’m testing a lightweight web calculation app (something similar to a gratuity calculator that updates values in real time), Firefox memory usage slowly increases, and sometimes the browser even freezes if multiple tabs are open.

I’ve already tried:

Clearing cache and disabling extensions

Running in Safe Mode

Using hardware acceleration on/off

Still, the problem persists.

So I’d like to ask:

1. Are there any specific settings or flags that can help manage memory usage better for interactive web tools?

2. Does Firefox handle JavaScript-heavy calculations differently compared to Chromium-based browsers?

3. Any recommended performance tweaks for developers testing such tools locally?

Would really appreciate advice from anyone who’s optimized Firefox for this kind of lightweight, web-app testing.

Thanks in advance! 🙏 bold text

I have nothing but problems with firefox since the last new updates. Sites hang, gmail can't be accessed, it takes 100x longer for sites to load, firefox uses huge amounts of memory and CPU, etc, etc.

I am so fedup spending valued worktime having to solve firefox issues each time they decide to make updates - which seems to be more and more frequent. How can I roll back to a previous version and permanently disable any further updates?

I cannot locate Adobe Acrobat extension to install in Firefox, v143, operating within Windows 11. I had previously been able to install this extension in Firefox operating within Windows 10.

My shortcuts no longer appear on my homepage. This just started happening. Shortcuts are still enabled in my settings. I refreshed Firefox. The shortcuts reappeared for a while, then disappeared again when I closed/reopened Firefox. I am on Windows 11 O/S
