Firefox コミュニティフォーラム

Immediately after I downloaded the latest update 153.0.1 for Firefox on the Mac, I noticed an issue with the Clear Recent History request. Whenever I select Clear Recent History (under History in the top bar menu), the popup box that opens always shows it is "calculating" the data, even if I only visited one website and closed it (or left it open). If the Clear button is active, I will click it and the box closes, but I never know if the history was cleared.

However, many times, the Clear button is grayed out while the "calculating" is in progress, and it freezes up the popup box. I cannot close it or click on any other part of the screen. It appears to freeze (crash) Firefox. My only option then is to quit Firefox and reopen it. When I do, the popup box is gone. But I still have no confirmation that the history has been deleted. But after visiting one or more websites that I want cleared of history (news sites, etc) the issue reappears again as soon as I select Clear Recent History.

I have a whitelist of many sites that I allow to store cookies and site data. But for all other sites, I routinely clear my history when I am done viewing them. This issue has never happened before, so I'm wondering if it is a bug in the latest 153.0.1 update. Before I downloaded the latest Firefox update, I checked to make sure it was compatible with my current version of Ventura 13.7.8 on a MBP 2022. And the clear history issue never appeared when I was on Firefox 152.0.6.

Attached is a screenshot of what the Clear Recent History popup looks like when "calculating"...

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!

On some forums - not this one - I am unable to complete the relevant text box to compose a reply. EG the Devon forum: https://discourse.devontechnologies.com/t/sync-between-mac-and-ipad-works-and-iphone-not-working/87390/7 No text appears and the text box is completely inoperative. The problem is not confined to that site, but I have experienced similar on other Forums.

I use Ublock Origin which I thought might be causing a problem but disabling it has no effect, neither does disabling Little Snitch. As a result I've concluded this is probably caused by something in my settings but I don't know which or where to look.

Any suggestions appreciated.

Mac Mini M2 Pro; MacOS 15.7.8. Firefox 153.0.1 (British English)

I want to use passkeys while also using Firefox. I read an online article that says this function is considered to be experimental. If so, it seems that it is experimental only with Firefox. I'm able to use them on every other browser I have. Where is the Firefox version that supports them?

This keeps popping up on my website when I'm trying to watch movies or TV: Server Not Found. Firefox can’t connect to the server it's happening when I press any movie sites or TV shows, I've even gone to the settings and done no proxy and it's still not working, can you tell me how watch movies and TV's because this gets popping up Server Not Found. Firefox can’t connect to the server I am not a tech person says simple jargon will be, appreciated thank you.

Hi, My Mum who is tech illiterate has recent encountered a problem while browsing-

She is unable https://direct.asda.com/george/clothing/10,default,sc.html

and only this site, she can do so in private mode and on other browsers, I have tried disabling her 2 extentions, I have cleared her cookies, cache and browsing history for Asda Direct but it still comes up blank. She does not use a VPN, she is in the UK.

The only thing I could suspect is if Firefox's VPN is somehow activating just for that one site but I can't see it being on, I only say this because I have to turn off my VPN on my own device to access this site.

Any help?

Since last week there is a cookie that I can not remove in the Manage cookies and website data panel. It is called about.ef2a7dd5-93bc-417f-a698-142... There is probably more but that is not shown in my view. How can I remove that?

MY FIREFOX IS HAVING AUDIO ISSUES. THE VOLUME INCREASES BY ITSELF IT HAPPENS USUALLY IF I ENTER OR EXIT FULL SCREEN MODE, OR IF THE VIDEO OR MOVIE STOPS TO BUFFER FOR A MOMENT IT WILL COME BACK ON AT 3 OR 4 TIMES THE VOLUME. ITS A IRRITATING REGULAR OCCURRENCE. IVE TRIED SETTINGS, AND UPDATES BUT NOTHING SEEMS TO FIX IT. IT SEEMS TO HAPPEN ON ANY WEBSITE I USE. (YOUTUBE, SEVERAL MOVIE WEBSITES AND CARTOON WEBSITES. ITS BEEN GOING ON FOR A COUPLE OF YEARS AND ITS VERY FRUSTRATING. I HAVE TO CONSTANTLY READJUST IT IN AND OUT OF ALMOST EVERYTHING I WATCH. HOW DO I FIX THIS ?

Dozens of reboots every day due to video seizures only with Firefox. Tab crashes causes those I am ordered to support to LOSE WORK. After a tab crash and restore the FF interface is frozen -- no type of input from peripherals possible. This is all supposed to be solved by Monday. If I am out of luck with FF -- just tell me. That's very simple. New machines, new OS and it's worse than under the legacy systems we support after moving up from Win 7 Pro.

Running on Windows 11. There are many supposed "solutions" on the Web, but none of them work. I have tried with: about:config, css files, etc. None of them work.

I like Firefox greatly, but this is so frustrating.

The developers have created a solution to a problem that didn't exist. The result is to make Firefox user clumsy.

It would have been nice if they - at the very least - had provided a way to change the 'Profiles' icon position on the menu.

Again, Firefox 153.0.1 (64-bit) on up-to-date Windows 11. Amd Ryzen 5, 6 core processor, 32 GB Ram, 500 GB SSD C drive = 197 GB free.

When I drag a URL from the browser to the desktop, clicking on it triggers a prompt, saying "Do you want to open this file". If I look at the general tab in the properties of the link, it says "This file came from another computer and might be blocked to help protect this computer". This happens on both of my windows 10 computers since they upgraded to the latest version of Firefox (153.0.1.) I need to check the "unblock" option in the link properties to unblock the link. This does not occur with other browsers.

images, text boxes dropdown menus and anything of the like reload the moment i scroll even slightly text boxes and dropdown menus dont reload text or option chosen just the image/ box no clue what could be causing it doesn't appear on mobile just PC. appears when searching with duck duck go and google also reloads when moving over images and a good chunk of the time only loads them partially/ flickering, not unusable just annoying thanks
