Firefox screws up showing .pdfs. The first view is fine but scrolling seems to overprint the first view without erasing it, if that makes sense, sorta like a double exposure. I can't get a screen cap either, which might just mean it's not a firefox issue at all, but I can view and screen cap .pdfs from any other application. I'm running Debian 12 up to date. When I need to view a .pdf I use Chromium, but I do prefer Firefox.

So I'm having a small issue with the volume slider on youtube. The gray bar that indicates volume is about 1% of the size it should be (Please see attached image). It functions fine but bothers me enough that I've contacted support. I've opened it in safe/troubleshooting mode and the issue persists, and there in no issue on chrome. Any help would be appreciated, thanks ^_^.

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

Logs out of email (gmail) after restarting the browser. I reinstalled windows and downloaded a browser, connected my account, and now when I go to gmail.com and register my mail, everything is fine, it works, but when I exit the browser and go back to gmail.com, there is nothing.

Since update to Firefox version 138.0.1, my last viewed side bar is never automatically displayed upon REOPENING Firefox. I must always > View > Re-select the desired sidebar choice >

How can I get this side bar to re-display automatically upon opening Firefox as it used to in previous versions?

When I publish an extension on Chromium-based browsers, I can select the markets/regions in which I would like my extension to be available. I cannot find this option in Firefox add-ons. Am I missing something, or should I assume that the add-ons are available for every region in Firefox?

When I log into my Outlook Web account, after putting in username and password, it sends me a verification number to my phone. When I put that number it the screen says "Logging out of Microsoft Outlook" and then takes me to the logged out screen. This was working fine until the last update of Firefox, and it works fine in the Duck Duck Go browser. It also works on my Android Cell phone.

I have been having an issue with Firefox opening certain websites and unfortunately my self and other friends are forced to use Chrome. It is even difficult to contact anyone at Mozilla on this issue. If we Mozilla doesn't show concern we will easily make the complete transition over to Chrome. This is the fourth time I asked for help and have tried trouble shooting the issue from posts listed. We are sick and tired of trying to get this issue resolved and have been with Firefox for over ten years. Does anyone at Mozilla care? No phone numbers, no direct contact? Why the hiding? Obviously we are all pissed off about this issue.

How to remove unlinked labels from bookmark organization ?

Deleting accumulated labels for deleted bookmarks

Good day,

I organize my bookmarks progressively, categorizing them by folders and labels. The labels are stored (libraries - above all the bookmarks) within their respective folder "labels". I deleted some bookmarks a few days ago and noticed that I am unable to delete the labels which have accumulated and been automatically recorded in the "Labels" folder.

How can I delete these numerous labels that are no longer linked to any bookmarks ?

Thank you for your responses and suggestions.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________

After updating firefox from 128.8.0 to 128.9.0, no embedded videos will play (youtube, instagram, plex, etc...)

The only way to get them to play is to run the browser in troubleshoot mode. Even a fresh browser profile doesn't work. Disabling hardware acceleration also does not work. Tried firefox 137.0.2 and that also does not work. Downgraded back to 128.8.0 and videos play flawlessly again.

I'm running firefox on gentoo linux on a thinkpad x13s (arm64) which uses Qualcomm Adreno 690 graphics.

Anything I should try would be greatly appreciated. Thanks.

Until a week or two ago, Amazon Prime Video worked without a problem on my Firefox browser. Now I cannot get Prime Video to open any show, nor can I access previous episodes of any show. I tried removing all my add-ons, including all my ad blockers and making Prime Video an exception to the enhanced Firefox browser feature. Nothing worked. Can someone at Firefox fix this problem or tell me why it happened? I CAN use prime video without difficulty on Safari and Chrome.

I dread the days where FF has an updated version of something for me to install.. because this issue ALWAYS rears its ugly head.

I've been ignoring the updates since Feb and for very good reason because this time (138.01 or whatever) I'm unable to bypass these security certificate expired error codes that say:

"If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." I literally was able to access all these sites without issue until I downloaded your must have update. How is this fixed???

Should I just uninstall FF and go back to Brave? I'm so tired of dealing with this as a normal day to day, no coding/tech background, etc. internet user.

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?
