Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

I've tried EVERYTHING I can think of to fix this issue. When 'trying' to open a YouTube video in Firefox, I'm 'informed' that I'm offline - try reconnecting (or something like that). I'm NOT offline. Three other browsers have NO problem opening these YouTube videos; it's only Firefox. Can someone PLEASE come up with a REAL resolve to this issue? I don't want to give up on Firefox and go back to Chrome. But this issue is VERY annoying. Thanks to anyone who can provide constructive resolution(s). AL R.

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.

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.

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.

Online forms don't appear in Firefox (Windows 10 PC), but do appear correctly using Edge or Chrome. This has been happening for quite some time. I have o switch to Edge or Chrome to see the fields to fill in on online forms.

I want to print a page. But without the header and footer stuff (because it is ugly and I don't want others to see the information). There are a lot of old pages here and on other places about how to do this. They are unfortunately all deprecated. What is the way to do this as of 2023? OS is Windows, btw.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

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.

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

the Ask to Save Website Passwords Option keeps Deselecting itself, it will not stay selected

Because of that, the Auto fill Username & Password fields do not populate.

I have already Uninstalled Firefox, removed all files from my system, deleted all Firefox App Data from my system, Reinstalled Firefox from Scratch, reconfigured all, but can not get this working correctly

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?
