When i click on the lock icon in the address bar, nothing happens (I would expect to see the encryption and certificate, but no widget opens). When I right-click into the page and select "View Page Info", "Security", "View Certificate", no certificate exists. Only generic info is shown (Servers+Authorities). Also an error is reported in the system log, confirming that no certificate exists: JavaScript error: chrome://browser/content/browser-siteIdentity.js, line 642: TypeError: issuerCert is undefined

Questions:

  • Why does Firefox show the lock icon while no certificate exists?
  • How does Firefox establish a secure connection without having a certificate? (From my understanding a certificate is needed for TLS to work.)

Version used: Firefox 78.12.0esr ('Mozilla/5.0 (X11; FreeBSD amd64; rv:78.0) Gecko/20100101 Firefox/78.0'), no add-ons or plugins.

When I go to google.com and do a search the results page has the "tools" button but it does not work. The "people also ask" categories are also broken (they will not expand), and, if I click the "images" filter button to view images associated with my search it either shows no images (or only a few images) and a bunch of blank boxes. I have found that if I hold the shift key and click the reload button everything is back and working properly until the next time I do a google.com search, then it is back to the same odd behavior. So, my assumption here is that either a cookie or some site data is corrupting the results page for my search. Running Firefox 92.0 (64-bit) on a Windows 7 Dell machine and everything was working fine until about two months ago. Also, Chrome does not show the same behavior. BTW. I have also done everything I have found that was recommended to fix Firefox issues with Google search. Run Firefox in private mode, run without plugins, changed themes, created new profile, I even completely uninstalled Firefox and did a clean install all with the same results. Any help is appreciated. It is almost got me ready to move back to Chrome.

Hi:

I am using the Safari browser on my Mac. Suddenly when I wanted to login into the Firefox account I got the 500 Error message that I pasted in the Subject. I am a new user of Firefox, just switched from Safari and I am not computer savvy...

I cannot login, I cannot create another account...

I hope I do not have to go back to Safari.... I have no idea what might cause this problem and what to do. I hope that somebody has the answer. Thanks in advance.

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

This new 'update' has just caused me to lose all my tabs and bookmarks. The new version is c**p and it is awful. I went to the page to install the previous version I liked and worked perfectly and when I installed I now have none of my tabs and bookmarks. My pc is nearly unusable and I am now out of business until I can get them back if I can. It will be months to try to get back to where I was and will never get all of what I had. Is there any way to fix this? I need help immediately.

Firefox Keeps Changing File Extensions for 'Odd' File Type

Like I said in the title, Firefox keeps changing the file extension for 'odd' file type when downloading them. I say 'Odd' because I download this type of file almost every day. They're a .ts4script file type, which is a file type for modding The Sims 4. Up until today they were downloading just fine, but now firefox keeps changing them into .zip files.

While this slightly makes sense as a .ts4script IS a zipped up file that contains python files it's very annoying to have to manually change the file type after downloading more than a few at the same time...

Is there maybe a setting I may have accidentally changed or something?

Hello there,

since the FF90.xx I can´t paste anymore in the World of Tank EU forum. I did refresh firefox and tried it without addons and in private mode and it does not work. The only chance that I can paste is in the mobile version from the used IP.Board. I can´t even see the paste/einfügen option in the posting section.

I have some other members inside the community that reported the same issue to me.

It would be nice to get some help/ideas.

With best regards.

Yesterday I went to my history to locate a prior site I had visited. There was only 1 site in history, which of course surprised me, and it was to CapitalOne.com/link accounts. This is my credit card company. I removed Firefox from my Macbook and then re-downloaded Firefox and installed. Nothing has changed. My settings are correct, meaning that I should be able to have sites visited in history, yet only the one site populates, and I've been to a lot of sites today....the credit card/link accounts site is the only site that is in history. You can imagine how nervous I am right now about doing anything on line. I sure hope that someone will help out here.
