Firefox Support Forum

Hi,

For the past month or more I haven't been able to open my Instagram notifications. Whenever I would click on "activate" on the notification's window the new window with this post would open up. Now it doesn't do anything.

I'm on latest Debian version and latest Firefox version.

For quite a while I am using Firefox and had no issues, but recently, with new version , I am constantly facing two issues 1. the initial load of a page takes more then 30 seconds , sometimes 1 minute, but after the first page has been loaded if I open another page , it will be as usual 2. Completely random and without any sign of slowing down the OS - the OS freezes - nothing works at all and I have to restart it using the power button. ( and this happens when Firefox is open so I doubt Firefox)

version Firefox Browser 91.0.2 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

I need the scrollbar widths to be wider. i have difficulty hitting them with a mouse anymore. Scrolling by hitting the area between the thumb and the (missing) buttons is just as hard, obviously, as it is the same, nearly invisible width. Using the buttons, oh yeah, like I said, they're missing.

I'm not new to this problem. I had this fixed in the past. I would fix it by changing CSS in one or both of two places: userChrome.css, and theming folders for my system. With the last update of FF the devil scrollbars returned, and since then nothing I have tried works. I'm aware of the legacy setting on userChrome.css and set that to true, with no effect.

There's a thread I could share on the Linux Mint forum where somebody asked about this a year ago, and I am not exaggerating, there were at least 10 different things to try.

I'm running FF 93 on Fedora 35 with a Cinnamon desktop. I don't want to do any more Google searches. Can someone point me, please to the DEFINITIVE answer on how to style the scrollbars, at least in my enivironment, and it would be really nice to not only get an answer, but one that will not become defunct when the next version of FF is released.

I installed Chrome, and scrollbars are usable out of the box.

Linux distribution: Ubuntu 20.04 LTS Firefox version: latest

I really, really need something to increase the size of all the icons in the toolbar. The size of the text is fine, but surprisingly the size of the icons is ridiculously small.

https://support.mozilla.org/en-US/questions/1260063

This thread does not help me, because for some reason the value '1.5' decreases the size, and the value '2' makes no difference at all.

A happy new year to everybody.

when i searched for " WebglAllowWindowsNativeGl:false restricts context creation on this system " in google, without quotes, i saw that at certain firefox version it has become disabled. but there is no explanation, why it was disabled.

https://support.mozilla.org/en-US/questions/1334668 "WebGL stopped working after the Firefox 88 upgrade"

https://www.reddit.com/r/firefox/comments/ky3m4l/accelerated_graphics_stopped_working_after_an/ "Accelerated graphics stopped working after an update ... firefox 84.0.1-2 -> 84.0.2-1"

somebody answers that users can enable it from about:config. i am responsible if i manually enable it. i want to know, why it become disabled.

Crash also happens when passed the argument `-safe-mode`. Does not happen in new profile. Crash happens both in v96.0.1 and after downgrading to v95.0.1. Console output mentions "Exiting due to channel error." I have not been able to find a way of increasing output verbosity.

I know and admit I stuffed up.

One day a long time ago I was prompted for my master password.

When I clicked in that area/field a requester popped up asking me to pick a colour. Confused I picked one - and a bad one I now see.

So now when certain parts of a web page are opened the background colour is this horrible colour and I can't really read what is there.

I don't understand what I did or HOW I did it.

This is a cropped example of the bad contrast I am seeing.

As I said, I admit I stuffed up. But this seems to all have happened since that one time with the main password requester.

Is there any way to enable/disable the "Allow pages to choose their own fonts, instead of your selections above" setting on a per-site basis? Thanks.

Firefox stalls and stops on youtube videos. Chrome, Chromium, Opera do not. Same computer-Linux Mint-only Firefox fails. Tried reinstall, tried all the answers on the internet, nothing works. I've used Firefox for years and never had this problem. Guess I'll have to move on unless there is a REAL fix for this

I do not wish to see advertisements for Mullvad on my Private Browsing new tab pages. But I can't even seem to opt out of them, as they remain even after searching "Sponsored" in about:preferences and unchecking all the applicable boxes. uBlock Origin also seemed unable to remove them, even with a custom filter and after enabling it on about-scheme.

So I went to fix it with userchrome CSS, by adding the following to a file named userChrome.css inside a folder named chrome inside my profile folder (after setting toolkit.legacyUserProfileCustomizations.stylesheets to True):

[code] /* Remove advertisements for Mozilla VPN */ @-moz-document url(about:privatebrowsing) { .promo { display: none !important; } } /code

However, even after restarting the browser, these advertisements are still present.

What am I doing wrong?

I use Mint 19.3 and is attached to a hardware product Winston Privacy which due to lack of sales the piece of Hardware is no longer available but the Hardware I have has a Lifetime License in the firmware. My point is the tracking that Mozilla does seems to be very high with Mozilla even though I have turned off the tracking with Firefox. As you can see with the attached file 'ScreenShot1' Pie graph Domain 'incoming.telemetry.mozilla.org' is the majority of the pie which has a count of 61 blocks. File 'ScreenShot2' shows the actual number count for the Domain.

I would like to know if the preferences (found in about:config or prefs.js) are explained in detail somewhere For example, what is browser.safebrowsing.provider.google.advisoryURL? What values can it have? Why can't preference entries be deleted (not just given a value of "") by the user? Thank you.

While startup of Firefox I'm getting the "The bookmarks and history system will not be functional" error message.

All because Firefox seem to be too stupid to follow a correct symbolic link to place (on another drive) where the file exist and has propper permissions (is accessable).

Thereof, please notify the developers about the described above bug, that it can become quickly fixed. Thanks

Hello. I want to report a performance issue (slowness) caused by the overexcesive virtual memory usage by Firefox sub-processess.

State description

After runing Firefox, I observed in the htop the process of Firefox (and it's sub-processes) and compared it with the about:processes

I had discovered that main Firefox process opens many sub-processess that aren't even used (they does not appear on the mentioned above "about" page).

Additionally, in some mement, at latest one of the created sub-process start to use 28.6 GB of virtual memory, like each of the created by it sub-process. This causes quite big loose of stability of the browser and even system

I am having issues with opening link for external applications. The application can be What'sApp or Zoom or Slack and when trying to open an external app I get a windows that ask for me to select the application to open the link.. When doing this the only option have I have is System Handler and Choose Application.. Neither option is helpful.. This did not happen with firefox packaged with .deb .. I am assuming that this deal with snap sandbox security.. I later read an article

I did a little reading and came across a link https://ubuntu.com/blog/how-to-snap-introducing-classic-confinement

Which instructed on how to create a snap with --classic confinement.. I am not sure if this will resolve the issue that I am having .. But I didn't find that I could install firefox snap with the --classic option.. I am not that familiar with snaps so I could be completely off but wanted to know if someone could look into it..

I would like to add an image but it doesn't seem like firefox will allow me to on this page. (Browse is not opening a window) Also copy and paste didn't work

I almost did not recognise my toolbar after seemingly an unattended install. It is extremely annoying with this wasteful double space harrange in the bookmarks toolbar on the browser menu. Why on earth do you want to add such large whitespace between bookmark entries ?

Hello, First let me thank Mozilla again for a great experience. I've been using Firefox as my main browser for many years and since some time I also started supporting Mozilla financially with whatever little I can with recurring payments. To the problem: since some time patch / commit view on HitHub with Firefox is broken. I guess many @mozilla have github accounts so you can open and read https://support.github.com/ticket/1318472 but to summarise: my first entry there was: ``` When viewing Linux kernel style Pull Requests on GitHub, using Firefox, TABs are displayed as 4 spaces, which is confusing, since the default is 8 spaces, which is also what is displayed in chrome and chromium. E.g. https://github.com/thesofproject/sof/pull/4747/commits/e9cc9312841a9329797b0b676335c8cb1a0dc779 ``` then a screenshot (attached) and a clarification to it: ``` As you can see there the patch area between lines 238 and 245 is wrongly indented by 4 spaces, whereas areas above and below are correctly indented by 8 spaces. ``` Then more: ``` No, space isn't used for indentation in that code. They can download raw code and verify, I'm sure they know how to do that. Why don't they just reproduce that themselves? Start Firefox, navigate to any PR commit like https://github.com/thesofproject/sof/pull/4884/commits/b19a64df2c2fcd63d7407ef500fd3312287c8995 and click arrows above and below the diff to display surrounding code. Then navigate to or download the raw patch https://github.com/thesofproject/sof/commit/b19a64df2c2fcd63d7407ef500fd3312287c8995.patch to see TABs used everywhere. Should be very easy to verify. ``` and their last reply was ``` From a technical standpoint this is not a regression. It's a problem with the way firefox interprets the combination of the tab-size css and the particular markdown we use for our diffs.

After reviewing the Issue in more detail there it has not been prioritized and will most likely not be addressed in the near future. ``` This is a deal-breaker for me. I spend hours daily reviewing GitHub pull requests. And I'd really not want to use a different browser just because of this... Please help! Thanks Guennadi
