Firefox Support Forum

For some websites, get the following error message: "Error: Secured connection failed. While connecting www.obelink.de, the following error occured: PR_END_OF_FILE_ERROR This web site cannot be displayed, because the authencity of the received data could not be verified" (Sorry - I use Firefox German version, so this is my translation of the German error message) I get this error mostly after Firefox update, presently: 102.0.1 (64-Bit) I tried to empty the cache, closed Firefox (Shft + Ctrl + Q), restarted - nope. Interesting detail: When connecting to www.obelink.de on my Samsung Tab A7 (Firefox for Android 102.2.0), the web site opens instantly. And the Android firefox is much faster that this here (Win 10). Can anybody help to fix the issue?

Hi,

So far this year, Firefox updates are causing problems.

Sometimes it updates in the middle of my seeing patients.

It used to give me the option of restoring all tabs. Now it no longer permits that option, so I have to painstakingly go through my recent history and add each needed tab - very time-consuming and annoying. I don't want to switch to Chrome but may have to as I have to use it anyway for sites that don't support Firefox.

I recently ran into a problem with firefox and amazon. That was fixed by uninstalling/reinstalling and using links from the 'old firefox data' file. Some things did not come back as expected so I did a system restore. The last restore point was before the problem. That did not bring back the missing items though.

One of the things that changed is the 'shortcuts' The shortcuts I used have mostly gone away and do not re-populate, so far. I liked the convenience of having this list of frequently used shortcuts and half the ones I always used are gone.

The recent activity links seem to be limited to 16 and are huge icons.

Now there was a change to the control bar top of the page. Specifically the download status icon. It used to show the download progress and terminate when the dl is complete. NOW, and I find it annoying, upon completion of the dl, a drop down list of the most recent downloads pops-up. Why? I do not need to see that list every time a dl successfully occurrs. And why is there no way to let it go back to the previous operation?

There is an old adage that software developers don't seem to get: "If it aint broke, don't fix it."

I cannot seem to reach https://community.esri.com/ via Firefox but can reach it fine with Chrome and Edge.

Firefox says "The page isn’t redirecting properly. An error occurred during a connection to community.esri.com. This problem can sometimes be caused by disabling or refusing to accept cookies."

So I even added the page to list of Exceptions, but still cannot reach site.

I just tried to open a new window using File, New Window. It is GONE. I always use that. Now all I get are New Tab New Container Tab (grayed out so I can't select that) New Private window, some other stuff.

The same is true if I right click. I get: Open Link in New Tab Open Link in New Private window.

What did I do to cause these changes?

I have been using Firefox for years and have always used Gmail as my default email account. Suddenly I can no longer open a mailto link - just on one of my several PCs. I go to settings and there is no option for Gmail or anything else. I tried copying the link from one of my other computers but there is nowhere to Paste that. Weird...

Hello there! So, I've just installed Firefox in a notebook I have and now there's a website where I can't see some pictures. https://i.imgur.com/E86dhVB.png There should be a picture there instead of (IMG:link) https://i.imgur.com/7lzrbfU.png There should also be a picture there, behind "Redvirux". Some pictures are shown, though, but most aren't. It's an http website, but it had been working fine on my Windows 8 instalation. Do I need some codecs? Is it a Windows 10 problem?

As the title says, ctrl+tab simply doesn't do anything anymore for me. All the other hotkeys (ctrl+t, ctrl+1, etc.) are working normally. I haven't changed any settings or installed any extensions lately. It still doesn't work if I restart into Troubleshoot mode.

I really can't figure out what happened.

HI for the past four days I have been getting the following error message when attempting to load www.canberratimes.com.au

"Application error: a client-side exception has occurred (see the browser console for more information"

This is happening on my Windows PC only. I can access the site on my Firefox browser on IOS.

I am running the most recent version of Firefox 102.0.1 (64 bit).

This is the only site displaying this message.

Grateful for any assistance in resolving this.

Kind Regards, Peter

Hey, Twitch dosnt work for me (error #4000) and neither do Reddit videos. Pictures and Youtube works and I could not find a solution online. Thank you for providing this awsome browser. please keep fighting for privacy.

An old question but seems like the about:config parameters have changed recently. the following don't exist anymore : toolkit.cosmeticAnimations.enabled ui.prefersReducedMotion

I've searched with other keywords but couldn't find the new one.

I was trying to use the sync function on my MacBook Pro. However, the browser does not seem to log in at all. In the top right menu, it still shows the "sign in" button, instead of my email address. (see the attached pictures which I captured from my mac and a virtual machine running Firefox ESR on Debian. Another test on the flatpak version on the vertural machine apears to be normal.

Checks on account activities indicates the login histroy exsits, yet the syncing function remains unavailable.

the browser on the Mac is Version 102.0.1 (64-bit) which apears to be up to date the browser on the virtual machine is Version 91.11.0esr (64-bit)

information for the systems and machines can be found in the pictures attached.

Hi, I'm back to an older computer where I already had Firefox installed. I have it installed and synchronized on 3 other computers and it works perfectly there. My main issue is that in the settings, Firefox is supposed to open with all the tabs I had opened when I closed it. It doesn't... It sends me to the home page. Second issue, also unique: I'm using Duck and go as search engine, and I have the same issue: it doesn's save my preferences (when it does on the same computer with Brave browser) Should I uninstall it all and try again? I already applied all the solutions suggested in th online help pages...

Thanks! Best,

I work with a laptop @home and have installed Bitdefender for security reasons. Today I had a warning (it's in Dutch, I do not know if that is a problem). Functie: Preventie van online dreigingen

firefox.exe heeft geprobeerd om op basis van een niet-overeenstemmend certificaat een verbinding te maken met browser.pipe.aria.microsoft.com. We hebben de verbinding geblokkeerd om uw gegevens veilig te houden, vermits het gebruikte certificaat voor een ander webadres werd uitgegeven. Toevoegen aan uitsluitingen

""It says something like firefox.exe has tried to make a connection based on a not approved certificate with browser.pipe.aria.microsoft.com. We have blocked the connection to keep your data safe. I can add this to exclusions"" or something like that.

I have never seen something like this before and I would like to know what it means and if I should exclude this, etc. So that's why I send you a mail to check it. Like to hear from you and many thanks in advance. Greetz Karin

Hi there,

All the icons on the taskbar when I open up Firefox have disappeared... and I now have the same "world" type symbol for everything. I've Googled and followed instructions, but I'm not seeing what the instructions are telling me to look for, so I can't make the changes.

Can you please send me a step-by-step on how to resolve this. I can't even 'open a page in a new tab'. That function has also disappeared.  ?????

I don't know what could have caused this. Would appreciate your help.

Cheers, Carolyn

Referring to this forum post, step 2 of the chosen solution no longer exists. Please help.

A few days ago, I tried to have one window for private mode and one for public. For Private mode, I used settings for custom history and Always use Private browsing Mode. Somehow, it didn't work. I'm old and forget a lot of what I did. I reinstalled FF a few times, to no avail. So did uninstall and told them why, and that I planned to be back in a few days. Also, I uninstalled the Maintenance program first. I went to EDGE, but really hate it, so I downloaded FF now. Set for Private browsing. But it doesn't work. Keep getting public browsing. Even if I select it on taskbar icon, no luck. Don't see the purple glasses or whatever they were. I really like to use private mode.

I can sure use some advice.

When I open the google maps website it functions normally for about 3-4 seconds, then firefox completely freezes not just that tab. Firefox is up to date and it happens with all addons disabled. maps seems to work fine when I access from other country domains (co.uk or .de) Also I have no problem with the site on other browsers. It does not generate a crash report.

When I click on "Show your bookmarks" icon in Firefox Toolbar / "Manage Bookmarks", it always opens "Other bookmarks". I want it to open "Bookmark toolbar" so I can quickly Edit resent viewings ?

The ">>" icon view is away too slow

How can I change this ?
