In many cases when one opens a new tab, the new one is opened on the right of the "parent tab". After reading the web page of the new tab, one often decides that the new tab is no longer useful and deletes it. Firefox automatically opens the tab on the right of the deleted tab, rather than resuming the "parent tab" on the left. This seems to be an ineffective design as probabilistically there are perhaps >90% chance one wants to go back to the "parent tab".

Q1: should Firefox change the default for resuming the left? Q2: is there a setting that user can change?

The New Tab Page is a fantastic tool. Are there any plans to allow more than four rows to their layout? I would benefit greatly by having 13 rows. Might there be any plans for that?

I don't know who thought it was a good idea to put someone who is pro-AI in charge of the anti-AI browser. I'm on Firefox because it doesn't use AI. You want to add in the most foolish, expensive, environmentally destructive, money sink that none of the userbase wants? Fine. I don't have brand loyalty. You choose personal wealth over the health of our environment and community by shoveling AI stupidity at us, I will drop this browser like a lead weight and switch to the lesser known browsers. I hear Waterfox hasn't bought into the slop yet. Might be time to change over to a more mindful system.

I have Linux OS Mint Cinnammon 22.2 and firefox 145.0.2 I have ticked "Save and auto-fill payment info" and my credit card ## are recorded. When I want to pay, the default credit card ## appear correctly, but if I click on them to apply, nothing happens. Every time I have to re-enter all the numbers ! Many thanks for your answer.

not really a request for help since release 147.0.3 searches handoff to awesome and can't be changed by using about:config dropping back to 145.0.2 allows prevention

My account won't sync my old passwords and browser history. I recently reinstalled windows and when I tried to sign in to my mozilla account my data wasn't there.

Today, all of a sudden, I lost my usual browser window that displayed all my bookmarks. The browser window looked completely different in a bad way and I have lost quick access to my most familiar sites. Moreover, the page displays sponsored ads, none of which is either of my choosing or of my liking. I am completely disoriented and Firefox has greatly disappointed me. Please help!

When I attempt to log into my ssa.gov account thru either login.gov or id.me with firefox browser i get the following message. "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." I can access both with google or edge. I am running windows 11 with most recent firefox update What do I need to change in my firefox settings?

Hi, I have 30 Firefox processes running and they are taking up ~2700 MB (84%) memory. I have 8GB installed memory. I'm running Win 11. What causes processes to run and how do I know which ones I can end?

Any help is appreciated.

Thanks, John

This afternoon, I clicked on a link from an email and for the first time got a choose a profile pop-up. I do not want this; I have read info on Mozilla and elsewhere about its purpose but it doesn't say how to just stop the pop-up - there should be an option just stop the pop-up because I don;t want to have to choose amongst options. I have started copy-pasting the links in emails and going to Chrome and will seriously have to reconsider using Firefox of this continues. I don't want to have to type about:config or anything - this should have been an opt out or opt in thing and I want out. Thank you for your help.

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

Firefox ver 145.0.2 (64bit)
