I use Kaltura to record lectures and post them to my course at the U of Utah on Canvas. This semester, Firefox will not allow me to open "my media" where the Kaltura recordings are posted on Canvas. I get the following message: It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve this issue, please update your settings to allow 3rd party cookies.

I copied the Kaltura web address 670542.kaf.kaltura.com that I can see in Chrome and pasted it into a Chrome browser and it goes to my recordings in Canvas when I use Chrome. The same site doesn't work in Firefox. How do I unblock Kaltura third party sessions? Thank you.

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.)

Hello, today I was surprised with a update ver.88 -> 89. It completely changed the look. Few weeks back it was similar with Thunderbird.

I hate this look. I want old look back - how to do this. I tried rollback to 88, but it ask to create new profile - after copying all content of profile it dose not work...

Is there a way to change look of 89 to look exactly like 88 ?

why why why .. again ..

I use the userChrome.css file to take the search bar from the bottom of the screen and have it float. Here's the instruction that I use ... .browserContainer > findbar {-moz-box-ordinal-group: 0; position: fixed !important; }. Firefox 107 has made that .css instruction non-executable. If I text out the instruction I now get the search box at the bottom of the screen. I want it back to a floating search box. Is there a fix in 107 so I can use my .css file or is there another way to get the search box floating. Regards

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.

All of a sudden, my bookmarks ( and other bookmarks) are double spaced. This just happened today and I didn't make any changes. How do I get rid of the double spacing ? Thank you.

I've noticed that with Firefox 102 when I download an exe file, in this case Thunderbird Setup 102.0.exe it is renaming it to Thunderbird Setup 102.0.exe.bin.

Why is that happening now? I know the "potential risk" or downloading an .exe file but shouldn't it ask or at least warn you instead of just deciding to rename it

I didn't see a setting to disable this "feature". Is there one?

Thanks

A short while ago, Firefox was automatically updated to 99.0.1 on my iMac running Monterey 12.3.1. Suddenly, for no apparent reason, the search engine is stuck on Amazon with no other search engine options available. I normally use Google.

Even if I go into the Firefox settings to the "Search" panel, it is showing ONLY Amazon as the available option in the pull-down menu under "Default Search Engine". In the "Search Bar" section, I have it set to "Add search bar in tool bar". But even if I set it to "Use the address bar for search and navigation", and then switch it back to "Add search bar in tool bar", Amazon still remains the only available search engine.

As a last step, I installed the "Google Search" add-on by 3Indian to see if I could get back my Google search engine, but Google still doesn't show up as an option anywhere, and I am still stuck with just Amazon.

Is this a bug in the latest Firefox build? Did the developers forget to enable something when they did this build perhaps?

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.

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

I am in the process of moving all of our passwords into 1Password. However, I discovered that my wife has her Firefox set to auto login, but can't remember her user name and password. So, although she can use it, she can't change update the password. The fact that on setup, auto login is the default makes this doubly frustrating. So, is there any way to get to the password?

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?

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

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.

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.
