Recently found one way to delete closed tab/window record: set both to zero.

Please allow users to select a timeframe as well. People may have to restart a computer while in private mode, and a set number of tabs/windows cannot cover all possible situations.

Thanks!

Hi everyone,

I run a construction estimating website where we share project-based cost estimates and detailed breakdown for contractors, architects

I’ve noticed a weird issue in Firefox lately.

Some of the heavier pages (especially ones with large tables, detailed breakdowns, and embedded content) start getting really slow or sometimes even become unresponsive in Firefox. The same pages load completely fine and smooth in Chrome, so I’m trying to understand what Firefox might be struggling with specifically.

I already tried the basic stuff like clearing cache, testing in private mode, and disabling extensions, but the issue still keeps coming back.

It seems more noticeable on pages with a lot of structured data and embedded elements, so I’m wondering if it could be a rendering, memory, or layout issue on Firefox’s side.

Has anyone dealt with similar performance issues on Firefox with data-heavy or content-heavy web pages?

What should I look into next: layout structure, CSS rendering, JS execution, or something Firefox-specific I might be missing?

Any guidance or debugging tips would be really appreciated!!

Greetings and Good evening Due to restoration of windows Mozila was uninstalled on 03/06/2026 It had all history and data since 2021 Please help me to restore this. Please tell me how this can be done? Thank you Regards Himanshu Kotecha Account id [edited] gmail.com

I've uninstalled Firefox and reinstalled it and cleared the cache. And it's still either not linking to certain sites at all or not, opening them correctly or completely. I don't wanna spend any more time than necessary on this since i've tried various ways to fix the issue.. If you can help me, that would be great. I guess I could use chrome, but I have used firefox for years.And as a rule, haven't had any problems up until now.

I am having problems with logging into the VPN app. I paid a one year renewal in November 2025 and have had access to the app for both logins that use this computer. It is an Apple M1 Macbook Air. On Wednesday, when I tried to connect, it sent me to a page to select a plan for payment.

Then when I tried to sign in again, it gave me the spinning circle shown in the attachment. It has now been a couple of days where I have not been able to use the app.

I do have access to the built-in VPN for one of my logins, but not for the other one. I have gotten replies from general support that told me to try the special support for VPN.

the top bar in the browser is so small it is hard to read and i find it difficult to access the icons. increasing the value of "layout.css.devPixelsPerPx" increased the browser text but did not affect the top bar. Is their another approach or is their a magnifier the will work. Thanks.

I tried using the private window option on Firefox to log into Walmart.com, and I was able to log in. This is a work around, but would still like to know what's causing this issue.
