I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

Canvas is working on all other browsers normally, but when I try to login on firefox an error 403 message shows up at the two factor authentification step. I allowed popups already in this browser so that is not the issue.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?

Hello everyone,

since my last update (125.0.2 (64-bit)), an additional website always opens when I open a website in Firefox. This is called "Page load error" in the tab; the content of the page is as follows:

Error: Connection failed

An error occurred while connecting to 0.0.0.1.

   The website may be temporarily unavailable, please try again later.
   If you are also unable to access another website, please check the network/Internet connection.
   If your computer or network is protected by a firewall or proxy, please make sure that Firefox is allowed to access the Internet.

How can I prevent this additional page from opening?

Thank you in advance for your help!

Greetings from Maria

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.

Hi, this issue has been present for a long time for me, and with many versions of Firefox Nightly for Android.

I'm always using the latest nightly for browsing Youtube only, with a set of specific settings and addons (since we can't use profiles on Android yet)

My problem is I've configured the Homepage to never show anything but a few URLs I chose to pin, you can see my settings and my homepage in the screenshots attached.

Despite the "Recently visited" setting being disabled, sometimes, but not everytime, the last pages I visited are added to the Homepage, after the pinned sites. I have no idea what triggers it or not, if I'm doing something wrong or if it's a bug.

Thanks for your help !

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

Since the latest upgrade to 115.10.1 (64-bit) I have an issue about running Thunderbird.

From a clean Windows 11 start up it is OK but then if I then Exit and then try to run the bird again it does not start.

Digging around I discovered using Task Manager, a number of Thunderbird processes run after I had Exited. See attached.

Any thoughts?

I have tried to restore a backup made with Mozbackup. This was a bad idea. I now have 2 profiles xxxdefault-beta and yyy.default. So I asked Tbird to install from yyy.default where i've got my recent emails and it tried to import without success. I humbly ask for some options. Can I merge 2 profiles ie copy them into one profie folder? Can I hide/rename the profiles then delete Tbird and install anew? I promise on my grandmothers skateboard I will never use Mozbackup again, + . As an aside in appdata,local,tbird,profiles,yyy.default,cache2 there's a whole bunch of alphacoded files. what do these do?

Ta.

About 2 weeks ago, Thunderbird stopped sending emails. I spent a couple of hours on the phone with tech support but was unable to correct the issue. Changed all of the settings several times, SMTP server, port, security and authentication without success. Tech support suggested using their server but that's a pain. Attached are pictures of the error messages. Thanks.

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.
