On a new laptop with Win11 Home (x86-64) with Firefox just installed, the cache size is 54 MB. When Privacy and Security -> Clear Browsing Data is clicked, Firefox hangs - no input is accepted and nothing appears to be happening. On closing Firefox and then reopening the cache size is reduced and Clear Browsing Data operates as expected.

Why is the cache size (54 MB) so large? Why does Clear Browsing Data hang Firefox?

I am running Firefox version 153.0.1 on a 64bit install of Windows 11.

A few days ago I had to factory reset my computer, including a clean Windows install. Since then, when attempting to access https://vodafone.cz/muj/prihlaseni, I get an Imperva Error 15 "Access Denied" error screen - screenshot attached here. Clicking the Imperva logo on the bottom of the error message leads to https://www.imperva.com/why-am-i-seeing-this-page/?src=23.

I was able to access the site in the past, most recently on July 8, 2026 - this would have been Firefox version 152.0.5.

This error persists in troubleshooting mode but not in private/anonymous (with or without extensions enabled), nor does it appear in Microsoft Edge or Firefox on Adroid.

Clearing cookies and cache did not help - in fact the error first showed up on a clean install of Firefox, when there weren't any cookies or cache stored yet. I've tried different DNS over HTTPS settings and listing the site as an exception in settings, but none of this made a difference. Enabling Firefox's built in VPN also made no difference, regardless of the selected location.

I found a recent post (https://support.mozilla.org/en-US/questions/1588627) describing a similar issue on a different website and tried the suggestion listed there to try a fresh profile - this seemed to work, but within a couple of minutes of browsing the error message returned. I've even reinstalled Firefox entirely, but this too did not help for long.

Interestingly enough, the error message lists a proxy IP address (not blacked out on the screenshot) despite the fact that I am not using a proxy.

The website provider's tech support claims this is an issue on the user side, not theirs - they have not been able to replicate the issue.

Is there anything I'm missing that would explain why this is happening?

Thanks!

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

Personally I do not like the new firefox. My bookmarks will not open in a new tab automatically when needed, it over rides the current tab that is opened. Additionally I am constantly being bothered with a unrelated pop up every time I open a new tab. and the Firefox logo used to appear so that you could click on it and get to firefox's home page. New version is horrible. may have to abandon and use another browser.

I downloaded and installed the latest version of Firefox. Every email link in my mail.com email.com account now fails with this message: Error Code: SSL_ERROR_RX_RECORD_TOO_LONG No Firefox setting changes are helping, but if I forward that and other emails with a link to another mail account I have, they links work perfectly fine. So I ave to conclude it is a Firefox issue, but I don;t understand how to fix it. Can anyone advise me, please? [redacted] @writeme.com

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

I often use browser history, but yesterday I tried "show all history" and got a complete blank. ALL history was gone. Moreover, the sites I browsed today are not being recorded in history! How can I get it to start recording my browsing again. I'm not as concerned about restoring all the history that has disappeared - but it's nice if that could be done.

My question is how do I temporarily remove my bookmarks. I have many bookmarks, hundreds, and I want to disable them temporarily for a few days so they can't be seen by another person using my computer. How can I disable them, but then make them all reappear a few days later? Can someone help? Appreciate the help. Thank you.

The VIEW tab in my Firefox will/can read some links and articles to me. It is wonderful.Choosing 'READER VIEW' in the VIEW tab. But some it does not. I'm hoping some AI will have this feature.- speaking it to me. Thanks.

Ever since I updated to 153, the FedEx website goes unresponsive after it pulls up a tracking number: I have to force quit Firefox to get out of this problem. No other website that I use has this issue. Everything else works just fine. What could be the issue here?
