The time zone stamp when using my default browser Firefox is 3 hours off. If I use Safari, it's correct. The problem occurs when using Gmail or Yahoo. It is only when using Firefox browser that the time stamp on email in incorrect. It is a Firefox issue and happened during the most recent upgrade 5/12/26.

“Whenever I play YouTube videos in Firefox, the playback stutters and becomes choppy. This happens even at lower resolutions (e.g., 480p). I’ve tested on Chrome and Edge, and the videos play smoothly there. I’m using Firefox version [insert version number] on [insert operating system]. I’ve already tried clearing cache, disabling extensions, and updating drivers, but the issue persists. Could you help me troubleshoot what else might be causing this?”

Hi all,

After the last update the former Mozilla Test Pilot "Snooze Tabs" isn't working for me any more, I tell a tab to snooze and it just stays where it is. https://addons.mozilla.org/en-GB/firefox/addon/snoozetabs/

I've tried running with addons disabled and then running with addons active again and the behaviour is the same. It's the same behaviour whether I run from the toolbar or the context menu.

I'm presuming this problem is related to Firefox update mechanics. Any suggestions for how to get this working again please?

Cheers :)

I've done recent updates (May 2026) and after having 3 updates in recent months, I still have difficulties with my video programs (both Zoom and "One-click) slowing down during my work which is 100% virtual. How can I revert to an earlier version where this was resolved, please!!??

I subscribe to MarketSurge, a stock data platform. It has run reliably on Firefox until last week. When I enter a stock symbol it brings up this error, and does not give the requested stock data from the MarketSurge live data platform. "[Autosuggest API Error] Failed to load info for symbol 'TTMI' ".

Has anyone seen that error before? Does it suggest a conflict within Firefox?

I have tried many things to troubleshoot and find the cause within Firefox, its settings and variations, and with Win 10. Nothing resolved. However, executing the Marketsurge platform in Chrome does not have a problem.

Background & Details: 1) Win 10 pc. with current updates. Firefox browser with current updates. 2)Firefox cache, history, and browsing deleted. Standard protection setting off. 3)Vpn off.

I would be deeply grateful for any insights re:Firefox that might be causing this problem, which did not exist prior to last week.

Thank you very much.

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

• Refreshed Firefox
• Created a new profile
• Uninstalled Firefox leaving my old profile
• Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

I have been with Mozilla since Netscape 1. Recently, I have been unable to add or delete a bookmark or folder. A number of previous bookmarks have lost their icons and their content. The Bookmark "Star" turns blue, indicating that it has been bookmarked. When I look for it in the designated folder it is not there. I try to edit garbled bookmark URLs by substituting the new URL - does not work. There are a number of folders for categories of bookmarks and I cannot delete them. What can be done?

Greetings. Have Windows 11 Home . I have noticed in the last month that when I click on the star that Firefox is not saving my bookmarks. I have searched online for resolution to this problem to no avail. I am up to date on my version of Firefox . Could someone please provide the steps necessary to get this feature back. I have used Firefox as my primary browser for decades and the bookmark feature has always worked fine . Thank you in advance for your assistance .

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

Amazon Facebook Ebay National Lottery and others just refuse to load.I tried troubleshooting mode,it worked once and now it doesn't.I believe I'm not the only one with this prob. Help? Thanks.
