When switching to another app from Firefox and then switching back to firefox, the webpage reloads. This is not a memory issue, I have enough RAM and it happens even if I only have 1 tab open. This is a major pain when I need to enter a 2FA code and need to swith apps to get the code. Or if I'm watching a YouTube video and get a call, the youtuve page reloads after the call has ended. Please suggest how to fix this.

Hiya.

So if I download an attached file on gmail using Firefox... it crashes. If I open up a new tab on Firefox... it crashes. It only started this week.

I'm using 12.7.6 and I really don't want to go back to Chrome, so I hope you can help.

The macbook completely freezes apart from the mouse pointer which moves, but cannot open a thing. Every time I have to turn the macbook off to restart it.

I tried uninstalling and reinstalling the latest version.

Best, Mike

Since Android 12, many apps can take "scrolling screenshots" that capture more than just the currently-visible part of the screen, with an aptly labeled "capture more" button. I noticed that when screenshotting a webpage in Firefox Android, I don't have the option to do this. When screenshotting the same webpage in a Chromium browser, I do. (See screenshots: 1st is Firefox, 2nd is Chrome)

Is this a bug, or a known FF limitation? Is it on the devs' roadmap?

I only opened 5 pages (fixed tabs), and only enabled two plug-ins, Proxy SwitchyOmega and AdGuard AdBlocker. The browser was always open, and the pages were static, and nothing was playing. The strange thing is that it didn't take up much memory at the beginning, but it took up more and more memory over time. Today the system got stuck and couldn't respond (it might be that the system used virtual memory).

I used the browser's task manager, which showed that the Shared Web Process memory of several pages was very high, some as high as 4G, and the GPU memory was also higher than before.

I think this is very strange. Why does the memory usage increase exponentially after the webpage has been there for a while?

My settings and usage habits have basically not changed. I didn't have this problem before, but it has appeared in the past six months. I have updated many versions, but the problem still exists. I have always used Firefox. If it continues like this, I will be very disappointed and have to make changes.

When scrolling on iOS, websites are jumping up and down whenever address bar appears. On some websites it isn’t a big issue (cnn.com), on some it is really annoying (Audi.pl). It makes it really hard to browse. See the video:

I have an e-mail in my TB in-box. The mail contains a hyperlink to Facebook. When I click on the hyperlink, I get the message copied above in the Subject of this problem. In almost all cases, if I re-click on the icon in the e-mail, the re-click takes me to the desired URL in Firefox. My Thunderbird is 128.11.1esr (64-bit). Why is the first click producing the error message? Would there be anything in the TB Error Console?

Regarding the current state of Firefox and WebUSB, I have four thoughts:

1. Yes, Mozilla's concerns regarding the security risks are valid, but not insurmountable.
2. In my experience, this is the single W3C noncompliance that impedes my use of Firefox.
3. In my experience, an increasing number of companies/organizations are leveraging WebUSB, from core-functionality of end-user hardware to enterprise-level troubleshooting, configuration, and support.
4. If Mozilla permits the use of unsigned plugins for its Firefox Developer Edition because of the reasonable expectation that its users understand the risks, it stands to reason that the same could be said for WebUSB.

(There's no need to reply, really - this is only being publicly posted because there doesn't seem to be a way to do otherwise - I just wanted to go through the exercise of casting this message-in-a-bottle into the sea.)

I keep getting a pop up when opening my mail that reads, "The folder on inbox (then gives my email address) could not be compacted because writing to folder failed. Verify that you have enough disk space and that you have write privileges to the file system and then try again".

I don't understand!!!

I am at a loss as to why this started to happen only a few weeks ago after a years of working fine, and why it should happen at all:

given a link to an HTML file where the headers include content-disposition set to attachment and the server (NextCloud30) mistakenly setting content-type to text/plain, what downloads is not the HTML file, but a text rendering of that HTML file, which is, of course, completely useless to the purpose and makes no sense whatsoever that it should happen. Why would anyone download a file and expect to the be interpreted?

But more to the point, how do I stop this behaviour. The above link, on my home cloud so be gentle, will work just fine on Firefox/Linux, but on Firefox/Android it will download as a 7k rendering of the file, renamed with the txt extension. The link itself is just a few holiday classics in the iRealPro format, which is, sadly, and HTML file. Up until two weeks ago, I would post a link in our band group chat, band members would click the link, be asked if they should launch iReal, and then iReal would ask if they would like to import this playlist.

what happens now is I post the NextCloud public link, they click and get a landing page that correctly describes the file as 20k HTML and has that previous link as the Download button. Clicking that gets you 7k of useless text.

I can't say for certain that this is a few 'feature' of a recent Firefox update or something that was changed in a minor update to Nextcloud. I believe it may also happen on Safari, but I haven't confirmed that, all I know is the link does not work on mobile for most users.

Here are the headers that curl reports, although I don't think Nextcloud gives me any option to change these:

All of a sudden my Firefox app is crashing. It will show the home screen fine but other than that, it crashes. It worked only an hour ago! I even deleted it and then redownloaded it via the App Store. It still crashes!

How can this be fixed? Or must I leave Firefox for good?

On websites, thumbnails will not display but appear instead as white boxes with small blue question marks. I am using a two year old ipad and my internet speed is 180.

This is a new bug, as of today.

If I click on each thumbnail the image displays just fine, but that is not ideal.

On a reddit forum, someone suggested typing about:config into the search bar but nothing happens when I do that.

Any ideas?

Am getting this message along with a recurring download of a specific email (keeps coming back even after deletion) that does not allow any other new messages to be downloaded. I do see new emails on my phone but will not read into Thunderbird??

Error: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

Tried: Troubleshooting, closing Thunberbird and reopening, rebooting windows system, compacting, etc. to no avail....

I bought a new android (Samsung) tablet. I want to sync all the tabs I have on my Windows PC to the tablet. I am not tech savvy.. further, why can't the Firefox page that shows all my saved tabs and bookmarks look the same on my tablet? sheesh...

Since I am on my new Phone (Xiaomi Poco F6, Hyper OS 1.0.4.0, Android 14.UKQ1.240116.001), I have this weird thing with Firefox that when I minimize it and then come back a few seconds later, it will automatically reload the tab I was on. Which is extremely annoying because, for example, I was on the Paypal page and was getting my login code from messages, then when I got back on the Paypal page it reloaded and I could not insert the code, but had to click on 'send code' again (and again and again). I saw this issue appear multiple times apparently already on reddit and co. But nowhere I could find an answer to it. Someone? I looked in the battery saver settings and in firefox settings etc, but I can't find anything that makes tabs reload automatically and it makes no sense that anything would clear the cache every time I minimize firefox, no?
