Firefox Community Forum

Hi everyone! Help me to solve the issue to get rid of these two folders in sidebar and drop-down menu. Is there any kind of tweaks css? I use Firefox 130.0 version. Look at the screenshot https://imgbox.com/fjL97vAX

This link https://support.mozilla.org/ml/questions/1389957 helped me but not for all cases.

I want to create a list of allowed web sites in settings/cookies&data/manage exceptions, but it seems I have to enter each site MANUALLY. I would like to do this more quickly and easily by just selecting sites in the "manage cookies" list and designating them as exceptions. Or is there already some other way to do this that I haven't found? Also, after I have made exceptions for all my important sites, by whatever means, can I assume that I can press "delete all" in the "manage cookies" list and the allowed sites will not have cookies removed? What happens to exceptions if I select "delete cookies and site data when Firefox is closed?" If there is no way to make exceptions other than manually, I respectively request that some convenient method be added to the program. Thanks for any response.

I'm a web developer, writing PHP on a Windows server. When there is a server-side error, Firefox doesn't give me any useful information, it just says "There's a problem..." (see picture) Well, yes, I know, I'm the one who did it, but I need to know exactly what the problem is.

NOTE: error handling and detailed error pages are turned ON - this is not a server issue.

FF behaves this way in both normal and private windows.

Chrome/Edge/Chromium show me the full error message, Firefox does not, as you can see in the images. I prefer Firefox's developer tools to Chrome's, but this destroys my productivity as I have to stop, switch browsers, copy/paste the URL, go back...and so on. I'd rather not switch back to Chrome if I don't have to.

Is there a setting in Firefox that will let me see the server's information?

Pacific Gas and Electric (PG&E) no longer supports Firefox. Please contact them and try to get them to support it. Otherwise I will have to use a Chrome, which I don't want to.

Since updating Firefox today and setting my profile as the default (since the update required me to make a backup) I haven't been able to click tabs. I can make new tabs and open link in new tabs, but i cannot click from the main tab that opens when firefox opens to any other tabs, ctrl + 2 also doesn't work. I can't even open settings because it automatically opens it in a new tab.

It looks like they are loading correctly, since i can see the mini popup if I hover over the tab.

Normally when i open firefox it open on the same tab/application image on my taskbar. however today it opened on a different tab/application image on my taskbar. i found this odd as this happened when i used chrome as well, when i used my secondary account it opened a new chrome tab/application. im just wondering if this is normal or has happened to anyone else, as when it opened the new taskbar widget my pinned tabs where also gone.

My bank uses FISERV to create their online banking. I can access all of the areas of their site until I print anything. Once I print the website no longer responds to my cursor. I have to kill the link and am not able to log off. The bank customer service says this is a problem with Firefox and recommends Safari or any of the other browsers. This is not just a problem with Macs but windows as well.

I have been using a usrChrome.css in my profile to create multi-row tabs. (Why cant Mozilla see the need for this with 4K monitors?) The Oct update broke this and I cannot get FF to load the css file that has worked for more than a ywar.

Help please?

The feature 'General > Show an image preview when you hover on a tab' is just a really great piece of work from Mozilla. I believe this fabulous feature first became available in the current version of Firefox, which is 131.0 (64-bit).

       The problem is that when this property is checked/on, hovering on a tab sometimes does not show the preview.  In this case it seems that, in order to regain this capability, it is necessary to click-out of Firefox, or even to re-start or shutdown my computer.  Any of these solutions make this important capability essentially unusable.

       I have observed this problem with Firefox on my MacBook Pro (2.8 GHz Quad-Core Intel Core i7) running MacOS 10.15.7 Catalina.

       This is such an important capability because in an arbitrarily complex tab environment it provides a naturally fast and efficient means of providing enlightening snap-shots of the current state of Firefox.

       Are there any other settings BESIDES 'General > Show an image preview when you hover on a tab' that need to be checked/on (or maybe even unchecked/off) in order to ALWAYS show the preview when hovering on a tab?

       Thank-you very much for looking into this issue and, if necessary, updating Firefox so that this capability ALWAYS functions as expected when it is checked/on, at the earliest possible convenience.

After the most recent Windows X desktop update (131?) Hulu/Disney logged me out of my account, and would not log me back in, despite changing my password. It also would not allow their chat bot to open a live chat window, I had to find a physical tech support phone number and get a live person on the phone, which wasn't easy, as they bury that number deep. After several frustrating tries with the desktop, they had me log in with Firefox on my Android phone, which worked, and on Chrome on my desktop, which also worked fine, so the problem is obviously with the Firefox Windows update, which I must say has been getting buggier and buggier with each progressive update and has been getting worse over the past 2-3 years or so. I will also say that MAX on Firefox crashes after every ad plays and between every episode, Amazon Prime has the same problem, and YouTube will refuse to play vids every 36 hours or so, claiming that Adbock violates TOS, despite Adblock being disabled, forcing me to log out of YT, and log back in, which fixes the issue for about 36 hours. Paramount+ also won't let me log in, in a similar issue to Hulu/Disney. So are there any fixes planned for these known issues? Or is Mozilla just planning on giving up and going out of business? They haven't seemed interested in fixing these issues for several updates now.

I've followed every guide I've found but the issue still persists. I've created a new profile, reinstalled ff after deleting the whole file from my pc, deleted all cookies for a dozen times, disabled all extensions, started ff in that problem mode or whatever it's called and I still can't login to certain websites. See attached photo. And Please don't blame this on the recent storm, this has been an issue for a long time now. We keep getting updates but no fixes. The only answer I've seen given is to disable all my security software, that's not going to happen. Microsoft edge has no issues with my security software.

Is it possible to change the font when printing web pages in the simplified format? It appears that the default font is Times New Roamn ... I would like to change the font to something more aesthetically pleasing.

A few times now I have suddenly found Firefox unable to load any web pages all while other browsers and apps on the same Windows 11 system continue to function as expected. At first thought it was IPv6, so disabled that at the system level to no effect. Additionally confirmed that DNS over HTTPS is disabled as our firewall blocks direct access to known public DNS servers.

Today however I have noticed that Firefox seems to get into this state after I execute some actions in Microsoft Outlook web (https://outlook.office.com/mail/inbox/) , which I do have running in a container specifically for work pages (Firefox Multi-Account Containers)

If I force-close FireFox and reopen it, it will continue to function as expected.
