With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

I need to shrink the size of my tabs, which remains constant no matter how many are open. If I have four open, I get the "+" for a new tab at the end of the tab bar. If there are five open, the tabs consume the entire width of the browser window and the "+" sign disappears. It is not found in the "customize toolbar" menu. I have tried restoring tool bar defaults and changing the uidensity to 1, but neither change shrinks the size of the tabs or gives me the "+" option.

What do I need to do to get back to the way it used to work?

I stupidly upgraded to the worst system in the world, Windows 11, and the silly animations caused serious strain on my device. I disabled the animation effects in settings, but now when I use Firefox as usual, the loading page icon animation has become a static hourglass icon, which is unfriendly. How can I enable the loading page icon animation while keeping the system animation effects turned off?

How do I enable container tabs? The option to open a new link in a container tab has disappeared and the prompt doesn't show up when I long press the new tab button either

Hi; Search engine does not open in new tab. This is not how it used to work. Not sure when this started, possibly when windows updated to Win11(2 weeks ago), but not sure. I think there used to be a setting for opening a search in new tab, but I can not find it. I have "Add search bar in toolbar" checked. I use DDG as search engine. I did lookup in FF help but found 10yr old answers. I am sure many things have changed since then.

Also when searching FF help is there a way to sort by newest first?

TIA

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

If you have multiple tabs open and you hit Ctrl-T to open a new one, it opens it at the end of the tabs, and the cursor focus moves to the URL bar so you can start typing in an address/search.

If you right-click on any of those tabs, it opens a new tab to the right of that tab, instead of at the end (which is what I want, as right-clicking on a specific one to open a new tab, to me, means you are linking those tabs in layout and want them together) BUT the cursor focus DOES NOT move to the URL bar.

This seems pretty counter-intuitive, and means that so many times I right-click, Open New Tab, and start typing a URL and then see that I have to stop typing, click in the URL bar, and start typing all over again.

Is there an about:config to force the focus to the URL bar, or is this a bug? If there's no setting for this, I would definitely consider this a bug because you have 2 different behaviors for New Tabs.

Currently i found the configuration for opening in the same tab, and that middle mouse will open a new tab. However, the new tab from middle mousing, just opens the same tab as where I middle moused. It does not appear to be loading/opening the link I clicked. Ive tried a few items in about:config but havent found one that makes it load the middle moused link.

Currently I'm using the css from this thread https://support.mozilla.org/en-US/questions/1341968 Now with firefox 113, this no longer works, I'm hoping someone can help me with this.

Same as this question, but the answer is outdated: https://support.mozilla.org/en-US/questions/839240

Is there a way to do this in the about:config page?

There is an answer about holding `Alt`, but that is a workaround.

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Hi Firefoxes! I updated to the latest and greatest 99.0.1, whenever i use the middle mouse button it opens every link in 2 tabs. Also when i middle mouse on a tab, 2 tabs are closed. Anyone came along this bug? Restarting FF and Windows did not help. Trying to get my notebook charged and check it on my macbook.

TYVM! Best regards, -John.

In short, "Open previous windows and tabs" is no longer working. I'm using version 111.0 (64-bit).

I have done the following: 1. Troubleshooting mode 2. Removed or disabled all my extensions 3. Refresh Firefox - twice! 4. Disconnect sync across my two laptops

Still, nothing is fixing the issue. My previous windows and tabs are not being restored.

Help, please!

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.
