Firefox-Hilfeforum

I have the bookmarks tool bar open with the ability to click on the two arrows on the right to see additional bookmarks. I have recently tried to bookmark some links like I always do and they don't show up in the toolbar. Anyone else have this problem? I did not change any settings. Did the recent update change some settings I don't know about or is this a bug. Any help will be appreciated. Thanks!!!

Why can't I use right click menu in Alert Dialog? I select the text in an alert dialog but when I press right click the menu will not show up. I works in Chrome. Why not in Firefox? Any way to have it work?

I'm all but finished with Firefox now. I have been loyal for years, but since moving to a new computer there have been multiple problems, especially with Lastpass password manager. Life draining.....

After many problems, I did manage to get it to work: IE: By working I mean that I would sign into Lastpass using the icon on the address bar. Then, whenever I opened a tab for a password protected website, it would auto-fill.

So, what has gone wrong now is that whilst I can sign into Lastpass (using the icon on the address bar), and the Lastpass dialogue box appears, instead of the dialogue box 'populating', it remains blank (as per the enclosed pic). Something has blocked it.

I think this started happening after I added 'AdBlock' to the address bar (I have now subsequently removed it).

And why did I have confidence in 'AdBlock'? Because it appeared in the add-ons in the Firefox menu, so I naturally assumed that this was a Firefox recommended add-on.

SO, I suspect that AdBlock has caused this problem, but I don't really know. All I know is Lastpass is not working, whereas it does on Chrome.

Will I ever get the hours back for time wasted writing this? Or the other previous merry hours of ‘fun’ just trying to restore the Lastpass icon onto the address bar. Simple? Not in a million years!....

Over to you. Do you care? Can you sort it? Or is this going to be the straw that broke the camel’s back? "Chrome here I come and bye-bye life draining Firefox; for this relief, much thanks"?

Gmail seems to be the worst site. Alphabet letters and numbers are missing from words and dates in subject lines. Same in the left folders column. Elsewhere, photos will not display properly. I'll only get bits of an image. Refreshing may resolve the problem momentarily but then it reoccurs. I reinstalled Firefox, but that didn't fix the problem.

Recently, in a month or so, YouTube comments fail to display, nor allow me to post comments. When I try to comment, it just close that field s if I've post a blank line.

Hi!

My system:

• Win 10 64 Bit Desktop, completely up-to-date
• Two windows user accounts: one admin account and one standard user account
• using Windows defender / firewall only (NO third party virus scanner / firewall)
• Firefox 87.0

The last day, Firefox worked without noticeable problems. Nothing special happened. However, on the next morning, the problems appeared all of a sudden on the windows standard user account (The windows admin account is NOT affected by the problem):

When clicking the Firefox icon, the Firefox window appears for a split second and then disappears. In Task Manager one can see the firefox.exe processes appearing and disappearing again. It seems that firefox closes itself or is closed by anything else right after startup.

There is no crash, no error message, no crash report. It is simply impossible to start firefox.exe, no matter in which way I try it:

1. Same problem when trying to start in private window mode or in safe mode.
2. Same problem when trying to start profile manager.
3. Same problem when trying to start firefox.exe from windows explorer.

I already tried all the standard solutions, but nothing helped:

1. Uninstall 64-Bit Firefox and reinstalled 64-Bit Firefox
2. Uninstall 64-Bit Firefox and reinstalled 32-Bit Firefox
3. I deleted all mozilla folders in all subfolders of %User%\AppData and also cleared any temporary files there (this should delete all user profile data and all extensions)
4. I did a complete virus/malware scan using ten different malware/virus scanners (MalwareBytes, Adwcleaner, TDSSKiller, MSERT, Sophos, F-Secure, Kaspersky, Bitdefender, Windows Defender, ESET), some of them started from external boot media (i.e. they worked without the need to start Windows). Nothing has been detected.
5. Disabling Windows Defender and Firewall as far as possible (meanwhile, I installed Bitdefender, so Windows Defender / Firewall are replaced)

I did a closer look using ProcessMonitor64, but I could not figure out any abnormalities (maybe you can give me hint what to look for?)

What I discovered:

1. Renaming firefox.exe to anything else (e.g. firefox1.exe) makes it work (but this is not a solution of the problem because Firefox updates will no longer work then)
2. The user of that PC starts Firefox by double clicking on the task bar icon. Usually, a simple click is sufficient. Could the problem be caused by a too slow double click (= interpreted as two single clicks) and a concurring start of two Firefox instances?

Any ideas?

Es wird immer gesagt "Bitte geben Sie Ihr Hauptpasswort ein. In English: "Please give your main password". As I don't have a pin I cannot complete the task. Could you please help me?

This is said about master password: Important: After you have defined and set your primary password, you will be prompted to enter it once for each Firefox session, when Firefox needs access to your stored passwords. This also applies if you want to add, remove or show a password.

I think that "when Firefox needs access.." should be changed to "regardless if Firefox needs it or not".

It would be much better if the master password promt was delayed until the first time it was needed.

After I updated from 86 to 87 Firefox lost all my logins & passwords, and will no longer remember passwords after I enter them. "Ask to save logins and passwords for websites" and "Autofill logins and passwords" are both still checked.

I got this message

C:\WINDOWS\SYSTEM32\MSVCP140.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f.

and firefox would either not load, and after I reinstalled it it would load but not load web pages. I refreshed firefox, uninstalled and reinstalled. Nothing so far. Even after a fresh install nothing.

I have seen the following question from 2017 but a not a clear answer. I do get to the "bookmarks manage" option (to import bookmarks). I don't have a bookmarks manage option. MC

Some websites including facebook (which is the one I notice it most on) and blogs don't load images or text correctly. At first some images, not all, would have yellow or green stripes going vertically through the images. Then things got worse and got yellow and green pixels. Now it is getting to the point where text is also looking like gibberish. This isn't everywhere, just on some pictures and some text. i do not have the same problem using other browsers. I do not have the problem all of the time. I have refreshed firefox. I have uninstalled and re-installed firefox. I have deleted cookies, etc. Nothing seems to help. This has been happening on and off for a long time but is progressively getting worse.

So my firefox used to have nice history tab and I could just with 2 quick clicks get into my whole search history and it had search bar but with recent update they removed it for no reason and I am really sad about it. I know that trough about:config you can do a lot with your browser So is there a chance to fix this ?

seems like there is a battle for browsers, I say that because I never had a problem with window 7. I open my page with fire fox and it askes me if firefox is my default and click yes and it freezes. Cant do anything at that point but delete it and do it again, and it happens again. How can I fix this in window 10?

when a download completes Firefox creates multiple tabs so they are rushing across the screen out of control

The doiwnload doesnt end up in downloads either

What can I do?

On all other websites I can seen the scrollbar buttons but not on Youtube. I'm running Windows 10.

On Linux Mint MATE 20.1 (and Ubuntu 20.10) the scrollbar also looks different from the default theme.

This seems to be a problem being caused by "youtube.com".

Why is Firefox allowing websites access to the scrollbars? Does anyone know why this happens or if there is a solution?

Thank you.
