When I turn off the windows animations in Windows 10 the font on Twitter.com changes somewhat. I believe it is altering the character spacing/scaling.

I have not had this behavior on other browsers (Brave, Edge, Chrome & OperaGX tested). I have not noticed this on other websites, but I also haven't really looked.

Windows version 22H2 (OS Build 19045.4291) Firefox version 124.0.2

Images provided are with them off, then on

Steps to recreate 1. Load a tweet (tweet in the images: https://twitter.com/FedeItaliano76/status/1779855670432408011) 2. Turn off window animations (settings->display->show animations in windows->Off) 3. Reload the Tweet

This is not a critical issue for me, but I think it's worth mentioning

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

I am unable to get printing to work correctly using Firefox with Epson POS TM-T20 thermal printers we have a work.

We're currently running Firefox on Debian 12. I've tried both the ESR version that comes with the Debian repository and the latest Firefox as a flatpak.

When printing to the receipt printer, the only thing that is printed is the left-hand most part of the logo and a little part of the text and this occurs towards the right-hand side of the paper. I've changing all of the settings, resetting the settings for the print in about:config, but nothing seems to work.

I'd love to get this working so that staff could use Firefox. I'm attaching an image of what the print job looks like and a screenshot of what the print-preview shows.

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

I've just noticed a "Tree Of Tabs" option. I right-clicked a dozen tabs, hit Bookmark This Tree. The webpages disappeared. Now I can't find them, and they're not listed anywhere in history or recently closed tabs.

I added the Save to Pocket (mini) extension to Firefox 125.0.2 today. When I look at the collection of articles I've saved to Pocket (I've been using Pocket for years) in the browser, I only see 8 articles. But when I open Pocket on my iPhone and iPad, the list of articles I've saved is much more longer (an estimate would be between 50 and 75 articles saved to Pocket). I haven't found any articles in Mozilla support to help me solve this. Thanks

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

Here is the extension i would like to convert

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

This has been happening for about a year now, I followed the guide and tried the troubleshoot mode and my tabs still crashes.

Can anyone help me read the crash reports and find the cause or common issue?

Here are the most recent crash reports I submitted.

Hi,

I have a question.

I just spent about 6 hours marking up a 39 page form using PDF editor. It worked great, but I’d like to know if I’m able to save my progress. I may want to make edits or changes to the PDF but don’t want to start completely over.

Is there an option to save the PDF in its current state so I can make changes or edits in the future?

I’m able to save the PDF as a PDF but I cannot find an option to save it for future use or edits.

Would like to know. Thank you
