trying to update old version of Firefox but seeing error code: ssl_error_no_cypher_overlap and the message "no common encryption algorithm" on a MacBook Pro with OS 10.5.8 - - not the machine I'm using in order to seek help

Hi, I've been trying to access academic articles through my university library online database. My browser often directs the shibboleth authentication to the sign-in page of my previous university, not to my current ones. An example is provided below: the first link gets automatically changed to the send one. How can I stop the browser from doing this, so that I can log in through my current university account? Thanks very much!

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

I recently lost all my data on my computer and after logging into my account, I couldn't retrieve my firefox data. I searched everywhere on my browser and couldn't find nothing to fix this.

Greetings.

Several times today I have had messages not sent because of this error message: "Did Not Connect: Potential Security Issue". I am sending political messages and am concerned that Mozilla is blocking me. I have sent hundreds of similar messages over the years with no problem.

What's up now?

Thank you. Sincerely, Gail Forrest

Ever since the last update or so (I'm currently on 145.0.2), simply opening a YouTube tab is enough to bring my browser to halt. Looking at the activity monitor on my Mac shows "FirefoxCP Isolated Web Content" using an insane amount of resources, multiple instances of 101% load on my late 2023 MacBook Pro (M3 chip).

Any ideas?

I downloaded firefox desktop for my imac 27" none of the passwords I had on file would work so I changed the password and tried it. It appeared to work but after a while the incorrect password came up again. I continued to try using the code you sent via email several times and even though it appeared to. accept the password it still rejects your code. I have tried both caps and lower case characters but it still rejects the login

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

Hello,

I am in a situation where I am a student at the university of Gothenburg. At the university the students have their own spaces at a cyberspace cloud storage facility. The place is called Canvas. In Canvas the students subject are lined up and information about each subject is also stored and other features about the students education. The place is only about university information and education. Yesterday, I tried to log in to my account into Canvas at the university of gothenburg, at Handelshögskolan on my computer. It was not a success. I tried to use the regular webbrowser for Apple, Safari, but it was not a problem there and I was able to login. I was also able to login to my account on my cellphone, which is logged in via an application downloaded from Appstore.

I do not wish to use Safari because it is not purposeful in the usage in the direction via education that i am looking to achieve.

How can you help me solve this please?
