When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

How do I return ctrl+c to just copying the selected text?

I have checked the extension shortcuts and not found anything there. I have also searched extensively for solutions, before making this post.

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

When I open the Manage Bookmarks in Firefox I have thousands (not exaggerating) of recently bookmarked items. How to I delete all of them? I think I turned that feature off via the browser.bookmarks.showRecentlyBookmarked. I changed it from True to False I have tried deleting them one by one but it seems like they recreate and I am not making any progress deleting. How do I delete all of them?

Thank you.

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

I removed the Firefox Relay, however whenever I want to open my email its still there and I have to keep entering my email address manually, How do \i get rid of it?

BEFORE ANYONE ANSWERS THIS PLEASE STOP AND THINK. I have been using this browser since Netscape. I have been "managing" bookmarks for years and years but I have NEVER found a SOLUTION to managing bookmarks in a SIMPLE, USEFUL way. I have wasted hours and hours on this site looking for answers to the ongoing difficulty that EVERYONE has dealing with the BROWSER WARS imperative that bookmarks can be imported and therefore, perpetually duplicated in an infinite array of browser upgrades and OS installations over the YEARS AND YEARS. For those of us who have managed to ERR on the side of caution and always opt to live with the effects of this rather than risk LOSING the good data nested within, I implore Mozilla to THINK LONG AND HARD on developing a solution to this ONGOING PROBLEM WITH BROWSER BOOKMARKS MANAGEMENT OVERALL. Oh sure, there are hundreds of plugins that ultimately suck up the memory for partial solutions to the PROBLEM that is caused by each new installation of Firefox or other browser in which past bookmarks are imported and ultimately duplicated ad infinitum. I don't need to know all the things that are wrong with Microsoft and how developers or users create the problem, I need a SOLUTION.

Will Mozilla please be the FIRST BROWSER TO SOLVE THE DE-SHITIFICATION OF BOOKMARKS no matter how poorly mismanaged and duplicated they were in past iterations?

The more time I spend on this HELP site looking for answers, the clearer it becomes that this is a problem for DEVELOPERS to solve because none of the USERS can figure out the answers. So, BEFORE you tell me ANYTHING, SHOW ME THE MOZILLA FEATURE THAT SOLVES BOOKMARKS MANAGEMENT THOROUGHLY AND SIMPLY, because, so far, that clearly does not exist.

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

Greetings, I experienced this problem with the prior update, now after the current update i get this" internal Server error" Hopefully you can straighten this out. I hate using Google for anything!

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.
