Hello!

A very important email folder in my Thunderbird just vanished. I didn't touch anything! My email was downloading very slowly and so I closed the entire Thunderbird application. When I re-opened it, the folder was gone. Everything else is there as before - all other folders, my inbox etc.

I have no idea what happened or where the folder went. I can't find anything online that addresses the problem or how to solve it. I'm very much a tech novice. I need a solution that a 5 year old could navigate lol

S.O.S. Cara

Hi, apologies I'm not very computer-literate, but my gmail has stopped allowing attachments such as images or files (just keeps saying attachments failed). I cleared a lot of old (large) emails from my email account and freed up a lot of space - but I still can't add attachments. I've checked Firefox and it's up to date - as are my ad blockers. Is there something else I can do like deleting Firefox and then reinstalling it to see if this helps - the problem is definitely when using Firefox (and not Chrome) as my browser.

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?

Just a few days ago, screenshot technique failed. I often copy an image from webpage. Right click technique. I am still able to do this. I have option of copy or Download. Download works but Copy does not. When I try to paste the copy into my Word document, I get a blank image (a square that indicates there was an image but the actual image is not there). How can I get the paste mechanism working again?

firefox changed and firefox nolonger lets me get my email, bank account, fidelity account, credit card account etc -- can you help me go back to my old firefox? thank you or do I need to start using another browser?

The thumbnails can be momentarily seen but within less than a second they disappear. Not happening in edge so doesn't seem to be a computer setting. Cleared all cookies and cache in firefox. No different. The attached image shows the pictures that are missing in firefox. Image taken from an Edge search.

Thank you in anticipation. Steve Balderson

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

This is a recent problem. I used to watch Peacock on Firefox with my ad blocking extension. Now I cannot watch Peacock videos. The page My Stuff displays but once I click on a program or episode to watch, I get the error screen. (see words below) Even with no ad blocker, I get as far as an ad beginning, and then the error. I have already refreshed my browser. This did not help. I can watch Peacock on Edge. (PC windows 10)

ERROR MESSAGE: Something went wrong. Sorry, your system configuration is not compatible with Peacock. Please check the supported devices in our Help Center (6007).

I have Windows 11 operating system on my Laptop, but when I order merchandise online via Paypal, I get notification stating my device was recognized and was using Windows 10! I don't understand why this is happening. How do I fix this?

I run a Synology DSM server on my local network. The website page to load locally inside my LAN is along the lines of 127.0.0.1:1001.

MacOSX 15.0.1 FireFox(FF) 132.0 (aarch64)

Previously accessing the DSM via the local IP address worked fine with no problems. Now, following one of the last couple of FF updates, I get an "unable to connect" message.

I also have a domain that routes to my local server and I can still access the DSM via the internet http address through FF. So I know that DSM is running fine and I have verified the settings within DSM.

I can load the DSM via the local IP in both Safari and Chrome. Only FF says it's unable to connect. So that shows that my DSM settings are fine and the page is available and loads in Safari and Chrome via the local IP.

I searched the forum and found similar postings, but not quite the same issue as mine. I deleted the cache & cookies/site data. I ensured the Proxy mode in FF is set to "No Proxy". I do not have any extensions running or themes.

I am at a complete loss at what setting in FF I need to change to restore this functionality.

Thanks, Matt

Some Firefox option is adblocking some links in Publishers Clearing House emails. The same emails work OK in Safari. There are no adblockers (now or ever installed) on this Mac. It's not the end of the world for me but it should be fixed for possible future use.

I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

please forgive me for asking again, but I REALLY need my addons to work. Firefox disabled my addons, forcing me to upgrade to a version of firefox that I don't need, since the old one was working just fine. The new version does not seem to appear to have downloaded properly, and neither version is allowing my addons to work or be re-installed. Please explain it to me like I am 5 years old, and help me to get this fixed without losing any of my info that might be stored in the addons.

 Thank you.

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.
