Firefox Support Forum

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

I'm having trouble using a particular site, that I used to be able to in particular clicking on sub menu's from a context menu if that is the correct term, meaning I cannot click an item/button to reveal a menu below it. From the image supplied there are 2 'menu's' with a < character that when clicked should reveal a sub menu of items, works in Edge/Chrome etc.. the only extension I have is Keeper.

Hey folks, I've been noticing something peculiar with Firefox that's been bothering me lately. Whenever I try to watch videos on YouTube in resolutions above 1080p, they tend to randomly buffer. It's quite frustrating, especially when I know my internet connection is stable and other browsers don't seem to have this issue. Has anyone else experienced this problem with Firefox? And if so, do you have any tips or solutions to share? Thanks in advance for any insights!

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

Hi, Today I discovered that firefox has logged me out of every site. I checked the cookies and there were cookies.sqlite and cookies.sqlite.bak. When I delete the newly created cookies.sqlite and rename cookies.sqlite.bak to cookies.sqlite, I am logged back in to all sites and everything works fine. I notice that the cookies.sqlite.bak file is created when I go to twitch.tv. Can I check what is causing this problem and fix it somehow? I've already tried deleting the cookies just from the twitch.tv site, but that doesn't help.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

in google and in other browsers when you have multiple tabs in a container you have an option to minify all tabs in the container. is there a similar feature for firefox,

thank you!

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

I had downloaded a couple of pdfs from google drive via private browsing which were stored in my 'Downloads' folder. But as soon as I closed the window the pdfs were deleted. I had also downloaded a zip file which wasn't deleted.

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?
