Restarted and still tabs on top ! argh TIA Jeff

I really want to disable that Firefox uses the mouse thumb buttons 4 and 5 as "previous page" and "next page" commands.

Example: Sometimes I study/play for hours a chess problem on https://tactics.chessbase.com/de/Solve but as soon the page gets reloaded it will be a new chess problem - no way to go back!

Somebody wrote a solution to disable the backspace key (on keyboard) triggering the "previous page" command, assuming the mouse thumb button 4 would be used by Firefox as backspace key. Unfortunately this assumption proofed to be wrong. The solution only disabled the backspace key to trigger the "previous page" command, but the mouse thumb buttons STILL DO TRIGGER the "previous page" and "next page" commands.

Where can I disable the mouse thumb buttons in Firefox - without disable the thumb buttons entirely in the Logitec software?

As there is no way to customize FF shortcuts, How to Disable them all together? In any way: editing settings, browser internal files, whatever. No, it's not about addon shortcuts. Yes, i already checked smt like a hundred topics/adviced addons web-search could provide, and none works.

I had to reinstall firefox and now I can't load gmail it goes to this page

I use the Bookmarks Bar extensively. But all the folders are the same color. I would find it much easier to find things quickly if I could change individual folder colors.

Any way to do this?

I'm already using Jscher's excellent UserChrome script to make the folders an attractive yellow, instead of gray. But can this be done for individual foders?

Hi,

I want to keep some sites cookies (exceptions) but delete all other cookies when firefox closes. I recorded sites exceptions, tried to set cookies or history managment but I can't have what I what

Sites preferences and cookies are not configured to be deleted in history configuration.

I drives me crazy, any idea ?.

All the best

there was a feature which allowed to stop smooth scrolling animation before it reaches the end and it allowed to stop it more precisely where you want it. With the last update-this feature was gone, why?

Hello, I'm using the latest version 83.0, 64 bit on Win 7, Ultimate The standard icons that every html and htm files used to have are not displayed anymore in the Explorer - the icon is just a white square with bent upper right corner. If I switch to Chrome or Edge as default browser they display properly. How to fix it?

On page https://support.mozilla.org/en-US/kb/html5-audio-and-video-firefox?redirectslug=viewing-html5-audio-and-video&redirectlocale=en-US

I find "AAC and H.264/MPEG-4 AVC are patented audio/video compression formats. They can be viewed in Firefox using built-in OS libraries (so neither Mozilla nor you need to pay a fee) if embedded in the MP4 container format (.mp4, .m4a, .m4p, .m4b, .m4r, .m4v file types)."

But when I create an HTML page with the following HTML5 code:

<!DOCTYPE html>
<html>
<body>
</body>
This is a test of video.
<video src="C:/MyVideoFile.mp4" controls>
</video>
</html>

I get the error "No video with supported format and MIME type found". Does Firefox in fact support .mp4 video? If so, what changes do I need to make in the HTML?

Hi all!

How to do multi-line Bookmarks bar after 84-update?

All code from userChrome.css that working on 83 update and has 3 working lines was crashed after 84, and bookmarks bar have only 1 line now(

Any body know how to fix it?

ps: sorry for bad english)

Trying to log in to spectrum > e-mail. Log-in to spectrum is fine. Link on that page loads the basic frame and links for the webmail page but the e-mail content does not load, where it should be is just white space, and the links in the frame do not work. This happens with chrome as well, on my desktop (win10) and on my laptop (Win7). I don't use the webmail often and so do not know when this might have started to be a problem - but it has not always been a problem.

The webmail page loads well with Edge.

Firefox is my main browser, don't use Chrome much. FF is up to date. Popup blocker for those pages is disabled.

What's going on?

I open a web page and soon after time page freeze (loading for ever) after some clicks. For example i open a page to order items to buy. After 2-10 clicks page freeze..and i open in new tab same page to complete my order. This is crazy. 2 months now same behaviour. Even tried refresh or safe mode...same behaviour. All other browsers work fine ie,edge,chrome opera. Using kaspersky antivirus and disabled all network security features but still same. Does FF need any incoming port in firewall? I am using FF for ever from first release, is my main browser and now start thinking to quit cause i can not make my bussiness with it. The pictura shows Mozilla Support tab still loading.

Hi, I'm searching an answer to my problem but, please sorry, I don't find it.

On some webpages, there is an 'internal' viewer for the images (or thumbnails).

With a pre-version of Firefox Quantum, on this webpage, for example, if you click on the images at the bottom of the page, the old FF showed the image with a internal viewer like in the attached image.

On the current Firefox, it asks me to view the image with the standard Windows imageviewer (or save it). Where is the option to open such images in the webpage iteself? TIA.
