Diễn đàn hỗ trợ Firefox

This issue started a few weeks ago. Frequently, when I switch from one page to another, I get a pop-up page from some unrelated business or form. I have started to fill out an order form for a trusted business only to find out I am filling out another company's form instead. My page gets hijacked in this manner several times a day. It's not only annoying, but a security issue. One moving company keeps popping up. I am not moving, or even thinking about moving, but I keep getting this company's home page when trying to access other venues.

I don't know if this is related, but I installed Duck Duck Go a while back to avoid Google trackers. A few weeks ago I found that Duck Duck was no longer my preferred search engine and put it back as preferred. Whether coincidence or not, my problems began about that time.

Please help.

When changing tags in Microsoft 365 Term Store, the changes are not showing on the respective Sharepoint sites and lists when displayed in Firefox. The tags still show the old values. Refreshing the page and deleting the cache does not solve the issue. Only uninstalling and then reinstalling Firefox resolves the issue. The problem does not occur in Microsoft Edge.

hi there

after the last firefox update i am unable to access my webmail at first, but now i have lost my firefox home page that has all my saved icons/shortcuts to frequent web pages.

at the moment i am using having to use another browser to access my emails.

if i want to go through the history/bookmark tabs i can find some of my saved web pages. still cant access my webmail this way.

i am running windows 10 for the moment.

thanks for your help.

I thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

Today Firefox has suddenly started using ~20% of my CPU capacity, causing my cooling fan to run high most of the time. Since I had been running Firefox v.149.latest, I tried updating to v.150.0, but that made no difference.

It's not Firefox by itself (only Task Manager open) but whenever I open another tab with almost any website (including this one) that CPU usage spikes. What gives?!

Details: Running under Windows 10 Pro (yes, I have installed the ESU package, good until thi8s fall) on a Lenovo P1 Gen 2. Currently running Firefox inside a Sandboxie Pro v1.17.4 sandbox.

bold text On brand new DELL Alien-ware laptop with Windows 11 Firefox sometimes takes 30 seconds to open, Also once it is closed it cannot immediately open again. Error message shows Firefox is already opened and asks me to close it.

In the task manager under Apps running I see Firefox(12) when only the home page is open. Are those 12 hidden tabs or 12 parallel applications?

Have I made some errors in the Setup?

A couple days ago I started getting a blank page for the Firefox home page. FF is set as my default browser and FF default for windows and tabs. The home page was working fine but now I can't figure out how to get it back.
