Firefox is showing me an older version of a website. When I'm opening the same site in other browser it is changes, but mozilla is still showing me previous version. what should I do to fix it?

I started noticing this after the firefox DLSS collab announcement. I have an OLED display. Sometimes the content is not shown properly like dead pixels or wrong places. One example i'm using claude, claude is generating result , orange rectangular boxes will appear over the text. If i scroll then i can read again. It's this glitchy experience in displaying content. If you are thinking it might be a issue with my display, no, i only have this problem with firefox. As i'm writing this a white box is placed over the address bar, then i switched tabs and it's gone. I don't know if it helps but i have 20 something tabs open. I also have a PC running Fedora, IPS display, I haven't noticed this bug there

Recently when i go to a new url in Firefox, it often takes me to the very bottom of the page right after it loads. For example, it just happened on fidelity.com. I haven't changed any app settings, but there have been app updates. Can anyone help?

Since 09sep2026, the "Currently" news area layout no longer displays text next to each photo. Instead there are vertical boxes with photos, then a short column with a few games, etc. boxes, then the right half of the page is blank. I have AT&T fiber internet service, which pushes "Currently". I have not changed any settings. I am still on Win 10, with an HP display. I have done all available updates to Win 10. Thank you for your assistance!

I am unable to open applications in Firefox. When I try to open an application, nothing happens or it does not load properly. I have already tried restarting Firefox, but the problem still exists. Please help me fix this issue.

I hopped over to the ideas page because I had a couple suggestions, and found I was not alone because lo and behold someone else had the same ideas. So I decided to agree by hitting the kudos button, but imagine my surprise when instead of adding to the number of users who supported the idea, this feature only seemed to reload the page for me!

I get the following error message when trying to access Microsoft Outlook.

Something went wrong server Error(/): GetSections returned no conversation history

I've already 1) restarted the computer, 2) cleared my cookies and cache, 3) re-started firefox in troubleshoot mode, 4) reinstalled firefox... none of those fixed the problem.

My font on some sites is being forced to this horrible condensed font and it's seemingly nothing to do with my font settings in browser. Thing is, I VAGUELY remember changing a setting SOMEWHERE to actually do this, but it's not the main font setting in accessibility. Furthermore this issue has only started happening in the last day or two and my vague memory of setting my font somewhere was years ago.

Is there any other setting in Firefox that affects default font for certain sites?
