I'm currently using Thunderbird 128.0.1esr (64-bit) on an iMac with Ventura 13.7.4. I have email correspondence in Archives on my Local Folder going back to 1998. On July 10, 2007, Mozilla phone support helped me get my Netscape mail into Thunderbird. For many years, I had no problems loading this old email correspondence in Thunderbird. I'm not sure exactly when it started, but emails from 1998, 1999, and 2000 no longer load. Also, I'm not sure, but it is probably all Netscape mail. I can still see the header information (sender, recipient, date, subject, etc.), but cannot open up the messages to read them.

Any solution?

Hi after MS installed the Feb 20 update Firefox freezes on pages particularly Youtube where a video will play but any click action causes it to lock up. Is there any way to refresh or reinstall FFox without losing bookmarks etc?

I keep getting error message "Something went wrong - Retry" when trying to reach an Audacy.com web page at https://www.audacy.com/stations/wccoradio . This does NOT happen when I use another browser (Chrome), but it happens about 95% of the time in Firefox. When I click the "Retry" button, it still gives me the same error message. I tried clearing out the cookies and cache but this did not help. I have attached a screenshot of the error message. Why am I getting this error message in Firefox but not in Chrome, and what can I do about it?

I have two different Apple Silicon Macs running macOS 15.3.1 and Firefox 135.0.1 and lately the Firefox menu (and the  menu) on the left side of the menubar have been disappearing after a while. Menubar items on the right side are unaffected. Clicking the menubar or switching away from and back to Firefox brings the menus back.

Has anyone else noticed this?

No idea if this is the right topic or not but I've been dealing with this frustrating issue where with some websites it just loads a blank white screen. I've tried every fix I could that I've seen on forums like this as well as on Reddit and nothing I've tried has fixed it. From launching in Safe Mode or changing things in about:config. Before finishing this post I tried launching in safe mode, so my add-ons and plugins are disabled and it still persists with websites loading in these blank white screens. I never had this issue at first and I'm sure it started to happen after an automatic update a while back.

I need this issue sorted out so I can look and compare items from shops but most of the time a website that works and I look at it elsewhere I'm dealing with this issue. No issue looking at stuff on the internet on my phone, though I do use safari instead on my phone.

I use Latest version of Win 11 and Firefox. My tracking setting of firefox for many years has been enhanced or strict. Previously only Firefox would allow me to search Ancestry , select something I wanted to download to my online tree. Lately I am unable to download such items; Ancestry flagging that there is a problem. On contacting them they advise to try another browser. O trying Firefox to Google to Ancestry. It works. But Norton is racking up cookies. Any ideas much appreciated. I am not PC expert and have a touch of dementia. Thanks. Derek W

I have problem when downloading Facebook to pen, it is always displaying this information. Hmmm… can't reach this page It looks like the webpage at https://www.facebook.com/n/?notifications%2F&aref=1740314262727807&medium=push&mid=62ece33d769adG5b082b9f73d9G62ece7d6d6c7fG32b&app=2522338851375423&n_sg=Q6bPBAG8gYND9MYjjrgYqawuJ-boOt53DCed9z6t9NtTfZKO7A might be having issues, or it may have moved permanently to a new web address.

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.

New system and firefox used to crash the tab, rather than the browser, but now it crashes the browser at the inevitable OOM situation

browser.tabs.unloadOnLowMemory is already set to true

I am trying to switch back to Firefox after having used it once before. However, I am unable to use the browser at all. I have to run it with administrator permissions for it to even open, and when it does open, I am met with a completely blank grey screen with nothing but my bookmarks. I cannot click any bookmarks, nor can I click anything on the sidebar [passwords, account, etc.] I can't search anything, and I can't use direct links.

I have uninstalled four times using Revo Uninstaller, removed all lingering data all four times, refreshed the browser, refreshed my account, changed my account password, run troubleshooting mode, updated my computer, updated my drivers, and updated the app. Absolutely nothing has worked, and I am still unable to use it.

I'm not sure what else I can do.

Firefox and Chrome

When I search for businesses and then want to see the phone number I have to click a ‘call’ button and that takes me to a pop up message (see attached)

With the question: ‘Allow this site to open the tel link with Firefox?’

But when I click open link it doesn’t work. So I cannot look up the business phone numbers! This only happens on Firefox and Chrome. On Safari the phone numbers show without the call button.

My main browser is Firefox.

Please help! Thank you.
