Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

Until recently (sorry, I don't know which version I upgraded from), entering fullscreen mode when playing back video (such as YouTube) would automatically force landscape mode, even with auto-rotation disabled. Now, there seems to be no way for me to enter landscape mode while playing back a video, without enabling auto-rotation (which I otherwise always keep disabled).

I realize that the desired behavior here can be subjective, but at least it would be nice if there is/would be a way of configuring this behavior?

I'm on Android 13 (Oxygen OS 13 on OnePlus Nord 2T), with Firefox version 112.2.0 (release April 24 on the play store).

I'm having an issue with Firefox on Android. On certain websites (e.g., Yahoo News, Calscape.org, Google search results--with Goggle Search Fixer add-on enabled), I can scroll down the page without issue, but scrolling slowly back up toward the top of the page with downward drags of my finger is only responsive half of the time. That is, I can only scroll back up with every-other downward swipe/drag of my finger. This odd behavior does not happen with other mobile browsers (I'm on Android 13 and using a Galaxy A53 5G). Any suggestions?

I've just installed Firefox 113.0 and my tab bar is now above the toolbar and bookmarks bar. Up until 112, the tab bar was below the bookmarks bar. I have no changed anything in UserChrome and in fact that file is still dated 2020. I've searched but haven't found an explanation. Anyone know what changed or is this just a bug? Thanks

I find the default view when searching for a keyword very overwhelming. There's a button that translates "show results as list" (my language is German) which leads to a much better view of the emails containing the key word. How can I make it the default search view? Thanks!

Hello everyone.

I've been using Firefox for quite a few years now and I'm used to keep my pinned tabs open after closing and then opening a Firefox windows.

Yesterday I noticed that after closing the navigator with the "X" in the tool bar menu, as I usually do, the pinned tabs are not "recovered" when opening again.

This happened randomly without configuration changes involved and drivers/firefox are updated to the last version available.

Moreover, I've tested the same in my notebook and it works just fine, as it keeps the tabs open when a new window is open.

Is there any troubleshooting for this or do you have any idea what could have caused this to happen?

Let me know if you need any additional info. Thanks in advance!

I just went to open Thunderbird and window popped up to setup email account. I have been using this for years. what the hell happened to my program for email? who has the time on checking email to set everything up again? Why wouldn't we be warned this was coming? Do I really have to set up all of my accounts again? What happened to my stored emails and folders that were setup? I am assuming the program updated, but honestly this pisses me off and makes me want to switch clients after decades of use.

hello,

i've facing this issue for weeks. i've completely abandoned windows server 2019 as daily os and installed windows 10 with latest patches. installed firefox and firefox developer as usual and did my same settings for years. but videos can't be played on reddit, twitter and linkedin. i tried to refresh browser, disabled addons (only ublock and enhancer for youtube is installed) to be sure. but still got nothing. in my laptop with same addons and same privacy & security settings could play videos.

linkedin: https://i.imgur.com/LPrBbuA.png

i can share everything that would solves the problem. thank you in advance.

If I want to installt he nightly version for Android on my phone. Will it be better to uninstall the common version before? Can the present settings, passwords and bookmarks be transfered from the common version to the Nightly. Any useful tips or recommendations, please? Thank you very much for the help provided.

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

Since the last Firefox update (I'm now using Firefox 113.0.1 64bit on Windows 11) when I play a video on Twitter, it plays with the right colors until I fullscreen it. When I fullscreen it, the video becomes darker and the colors are wrong.

• The same happens to youtube videos (both fullscreen or normal size): the colors are not right and they looks darker.
• The same problem happens using both my laptop's internal monitor and the external monitor.
• I tried to reinstall Firefox but it didn't fix it.
• I also tried to take a screenshot of the "wrong colors" videos using the Windows screenshot tool but the output image is displayed with the right colors and not with the darker ones.
• Using Chrome the colors are correct and I never had this problem before the last Firefox update.

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

I was having trouble receiving emails and I couldn't work out the problem. I deleted my mail account and re-added it. Now all my folders are gone. I can see them in my profile, but can't work out how to get them back into Thunderbird mail. Please help

I've tried everything to fix poor picture quality when streaming "third party" videos, e.g., YouTube. Colors are washed out; weird contrast; everything looks like it's coming through a haze. Streams from Netflix, Amazon look normal. And sorry, guys, the same third party streams from YouTube et al. look totally normal in the MS Outlook browser. Have tried all kinds of settings and rebooted as well. No change.

Please advise. This problem appears to be unique to Firefox.

What it says on the tin, booted up my computer, started Firefox, had it apparently update and then the tabs were suddenly like this. It's functional and just looks weird, I guess, but it really bothers me. Any way to fix it? Thanks in advance!

Hi,

Since the latest update today 102.11.0 (64-bits) my Thunderbird on Windows 10, freezes when receiving mail. I did a new install but that did not help, I have turned off every email notificiation, that also didn't help.

I have asked my ISP but they have no server problems with my imap account. On my phone, with a different program, I have no problem at all.

Is there anything I can do to get this fixed?

Thanks !

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

I had problems with thunderbird email text too small. Resolved that but now the title line with subject to and from is too large. How do I change it. Windows 11 latest version of thunderbird.
