[2022] Any way to change the color of individual Bookmark folders in the sidebar?

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

PlacesToolbarItems > .bookmark-item[container][label="Complete Tasks" i] {fill: #FF0000 !important;} PlacesToolbarItems > .bookmark-item[container][label="Medical Coding" i] {fill: #FF0000 !important;} PlacesToolbarItems > .bookmark-item[container][label="Bodybuilding" i] {fill: #FF0000 !important;}

This isn't that important, but I was just experimenting to see if changing a few folder colors would be of any benefit to me. And the above code that I tried didn't work. I'm guessing that something changed with Mozilla Firefox in the last 1-1.5 years, and I have a feeling that if I dig into https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors for hours or even days I won't be able to figure out what I need to change. Anyone know what the new code should be? Thanks in advance.

Since an update a few weeks ago, every time I enter an address or tap one of my most visited sites, instead of continuing on from the previous site, it opens a new tab.

I've scoured the settings but can't find anything. Surely this is a bug? I end up with 10 tabs within minutes. Can't understand what the purpose of this change is

Recently if I browse pages with maths forumulas they do not display coorectly, instead the underlying Tex or LateX code is shown.

I have several computers and I use Firefox on all of them, but curiously this problem does not happen on all of them, some show formulae correctly.

The image attached shows an example at Wikipedia - Lagrange point . The upper portion is Chrome and displays correctly, the lower portion is Firefox where the formyuals do not display correctly.

This is only started recently. Previously I had no issues with formulas displaying on any pf my computers, for many years.

Saw older replies here, but I don't have the technical expertise to understand them.

The 3D function in Google maps doesn't exist. The item to click on is no longer there. Is there a work-around or do I have to use Chrome now.

(It seems with each update I automatically get, I lose a function. I'd like to get a link to a Firefox version from at least 6 months ago.)

Periodically, randomly is all I can say, a message window opens when I power on with a statement about "UpdateBrowserForApp" having stopped working; and then I'm given options to close the program, etc. See attached screenshot.

Firefox is the only browser I use. Is this message from Firefox or does it mean I should do something related to Firefox?

Thanks for whatever info or help you can give. Lee

Recently I started getting an error saying SEC_ERROR_REVOKED_CERTIFICATE while trying to open a website. That particular site can only be accessed through my demat account so replicating my situation is not possible. Other browsers like Chrome, Edge are able to open it but Firefox cant, it does only when OCSP is disabled. I reinstalled the browser but the problem remains. Pls tell me how to add that website to exception if its possible or delete all the certificates currently loaded on Firefox or a full reset of the browser removing all previous data. And is it okay if I keep OCSP off all the time?

I normally use Firefox desktop on my Linux computer.

Last week, I started using it on a public computer running Windows. I installed Firefox Portable and then logged/synced into my Firefox account on this Win computer. I noticed that in the Firefox Portable Windows “about:preferences” page, it says “Your browser is being managed by your organization”, which links to about:policies. In that “about:policies” page, it shows this https://i.imgur.com/JmD8nXg.png Policy Name: DisableAppUpdate Policy Value: true. Now I’m back on my Linux desktop computer and it also has this “managed by your organization” message in “about:preferences” and the same “about:policies” stuff. In other words, it appears that this policy was copied from the Windows public computer to my personal Linux computer. I don’t want that.

How can I undo this? And how can I block this sort of policy syncing?

My windows theme is dark, but i don't want to use same for Firefox. I tried to set ui.systemUsesDarkTheme value as 0 in about:config. But problem still remains.

Is this a bug with new version, or a feature :)

I store all of my passwords in Firefox's "Logins & Passwords" feature. Even for things that are not online in any way. Whenever I need to create a new login & password record for something online, Firefox will automatically generate a password and give me the option to fill that into the new password and confirm new password fields. For anything that's not online I open Firefox and click the "Create New Login" button and fill in the details. I then go to a site online that generates passwords for me and fill that into the password field for the new entry.

Is there a way to get Firefox to offer a newly generated password at this point?

google.com and google related websites doesn't load at all. For example, gmail slowly loads, but loading icon never disappears, loading icon is always shown and then often it shows 'reconnecting' message. This works OK in Chrome.

Steps to reproduce: 1. Open Firefox without VPN - all loads well. 2. Enable VPN - stops loading. If I then disable VPN - it starts loading again.

If I restart Firefox it starts working OK, but after a while stops working again.

I use Firefox quite a bit and installed it on my wife’s MacBook air and I’m trying to get her to use it. I recently set up a gmail account for my brother-in-law who does not have Internet and uses my wife’s MacBook air when he visits us. 


A couple of days ago the mystery icon—Firefox logo with a tv screen on the upper right—started appearing on my MacBook pro every time she turned on her computer. There does not seem to be a way to get rid of it. Any suggestions?

Hi everyone,

I have the problem in the Subject line. FF sucks about 500 MB to be run, on top of which it takes 500 MB per tab, and that makes it impossible to run a research on my 8 GB Mac. Yesterday I was looking for a lamp and had no more than 7 tabs open, 3 of which were largely text, 2 were online shops, and 1-2 were websites with pictures. No Facebook or social media, no YouTube. FF froze, made the whole Mac freeze (well, Mac is garbage nowadays but let's leave that out of this topic), and I had to wait MINUTES before I could close it, because the computer was nonreactive.

When I check online, I see people being like "why can't it manage more than 50 tabs?". 50?!?! My computer dies with a maximum of 10 when it's only text websites!

So, I guess there's something wrong with this.

- I don't have many extensions (SimilarWeb, VPN, and Flash Player), I always use incognito so I can't use the plugin that allows me to use several accounts at the same time, so I can't see what's messing with my Mac. - The Activity Monitor (pretty much Task Manager on Windows) shows "FirefoxCP Isolated Web Content" for each tab, could that have anything to do with my problem? - CPU usage is very low, some 0.5 to 10% max during heavy use. - I seem to remember I used to have dozens of tabs open in the past, although I can't be sure. Is this a recent problem?

I really hope there's a way to solve this, because now I always fear that opening FF while on a Zoom meeting might freeze the whole thing.

Thanks to anyone who might want to shed some light on this big problem.

Screenshots: RAM and CPU usage with 2 tabs open. Two, taking more than 1 GB of RAM and about 250 threads in total? While using 0.2% of the CPU? I'm lost

I recently updated the SSL certificate for my business. My Firefox browser indicates the certificate is "not secure." When I navigate to my website using Bing, the SSL certificate shows as being "secure." I'd like the SSL certificate to indicate it is secure using Firefox browsers. Is there something I can do so that when someone lands on my website using Firefox it will correctly show that it is a "secure" site?

Thank you.
