If you lower mtu to 400 when using Firefox The problem occurs in the latest version 78.3esr.

The site doesn't open properly You can reconnect countless times over and over again, The page does not open.

This issue did not occur in the 68.12esr version.

There was no problem in the lower version even in the non-esr version. When the version was upgraded, the symptoms appeared. I've been using 68.12esr.

I can not speak English well.

Korea is a country that blocks sites using https. Adjusting mtu is a necessary measure for Koreans.

Hi

If I am opening bookmarks in a folder or sub folder from the bookmark toolbar sometimes I'd like to open several related ones at the same time but I don't want to open all of them.

Is it possible to duplicate the middle click behaviour for shortcuts on a web page (mine is set to open in a new tab but don't switch to it) in the sense that if I middle click on a bookmark from a folder (or sub folder of) on the bookmarks toolbar it opens it in a new tab but doesn't then close the bookmark folder I'm using so I can select more to middle click without having to navigate back to it.

Thanks

Reading the several comments on this subject has not led to a solution. The Firefox Setup 81 and Installer are sitting in the downloads file, but when I click either "Open" or "Run as Administrator" I get a Windows "For security and performance Windows 10 in S mode...." followed by two options "Learn more" or "Switch out of S mode". When I choose the latter the "Switch out of S mode" page arrives. Now what? Thanks.

I am unable to open My office email page, as well as www.brightmls.com on my web browser. I have tired deleting the application and re-downloading it, I have tried clearing out the history and cache, nothing seems to work. I would hate not to have Firefox as my main browser as these 2 websites are the important ones for me and I use them most often.

(Image). For some reason tif files keep asking me if I want to open them in photos or save them, I *always* need them to be saved and having to manually select "download" each time can cause some files to be missed in the process and thus not downloaded. This is a bit of a problem for me since in one single day ill download some 30 images total.

Any tips on how to tell firefox to always download tif files?

Hello Mozilla Community,

I was hoping someone could help me with a major screw up that I've made.

A week ago,I performed a Windows System Restore because I was having internet connection issues.I was hoping that my default settings would fix this.Well,when I tried to go to Firefox(my default browser),my bookmarks were all gone.I had read about a suggested move of the about;profiles on Firefox solution.When I tried this,there were only two additional profiles on my page and they were over 2 years old.I also tried going through the ShowAllBookmarks/Import And Backup/Restore method and it was the same results(old versions that were over 2 years old).I know Firefox had created a bookmarks folder in my computer files titled Old Firefox Data but that has the same result also(old bookmarks profile from over 2 years ago).

Also,when I first tried to access Firefox after the System Restore,I was asked to sign in to Firefox.I don't ever remember writing down a password for Firefox so I created a new one.I was hoping that my bookmarks would somehow automatically restore themselves but it didn't happen.Is it safe to assume that with my new password reset that I'm not able to access my old profile with all my bookmarks from two days ago? So basically,it currently looks like all my bookmarks are gone from the last 2 years.I've tried many tutorials and videos but it all leads to my only getting access to my 2 year old bookmarks.

Last,I looked into a recovery tool that I found while browsing a help forum.It just gave me a free trial run and scanned my computer for recovery files.When looking for the Places:Sqlite files(old bookmarks), I noticed that the scan produced some recovery files from Mozilla Firefox that were only a few months old.I tried to search for them on my computer but nothing is recognized through my Windows Start button search.I was also advised to use RECUVA to recover old files that have been deleted.I also tried this and saw many old Mozilla/Firefox recovery files but couldn't find any that had Bookmarks in the file description.And when I do find a 'places.sqlite' file, every time I try to open it with Firefox it just keeps opening up a new window and never opens the file.

In closing,any of your expertise would be greatly appreciated because I'm completely stumped and frustrated.Please let me know if there's anything that you can help me with.

Thank you for your time

Hello. I've been using Firefox 81.0 with MacOS 15.7. I opened FireFox recently and after a few moments it froze, so I had to force quit. When I tried to open it again, it told me that 'A copy of Firefox is already open. Only one copy of Firefox can be open at a time.' However, I only have one copy open, or anywhere else on my HD. When I click "Okay" to close the prompt, Firefox freezes again and I have to force quit. I tried deleting the application using my existing Profiles folder. Again, it froze. I deleted the app and the Profiles folder, used Safari to download a fresh version of Firefox 81.0, installed it, and it ran for about a minute before freezing. Again, I had to force quit. And again, when I reopen it, the same prompt: 'A copy of Firefox is already open.....' I Firefox froze when I tried to close the prompt. I can't even reinstall a fresh version of FireFox. I don't know what to do. I'd greatly appreciate any help. Thanks.
