After updating to Firefox 108, it's no longer possible to use gesture extensions on new tabs set to open "Blank page" here: Tools > Settings > Home > New Windows and Tabs > New tabs: "Blank page".

However, when manually browsing to about:blank the page still allows gestures. E.g. to close the tab, or navigate away from it.

Viewing the page source of the "Blank page", Firefox 108 does not actually open about:blank when set to "Blank page" but instead opens about:newtab.

Either about:newtab used to allow extensions to run and no longer does, or the behavior has changed so that it now opens about:newtab instead of about:blank when setting Firefox to open new tabs in "Blank page".

This breaks work flows of using a gesture to open a new tab and gestures to navigate away from it or close it.

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

I prefer to have all my previous tabs open when I start up Firefox, which means that I don't want them to close upon exit. Recently, Firefox started closing my tabs upon exit, even though:

- I tried both hitting the X and choosing Exit from the hamburger menu
- I have checked "Open previous windows and tabs" upon startup in settings
- I have not checked "Delete Cookies and Site Settings when Firefox is closed"

- I have the option "Firefox will remember history" selected

- I do not open in Private Browsing mode

What other settings do I need to change? Debra

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?

So I enabled push notifications for Google Calendar. Every time there's a notification, Google Calendar ask if I want to enable "Switch to this tab" for their notifications. I accidentally turned it on, then I managed to turn it off. Except it now keep asking me if I want to enable it.

Looking at the settings, the only two options available are "Always ask" and "Yes", with no way of just saying no... why?

I have "Open links in tabs instead of new windows" selected but links are still opening in the same tab. I understand not all websites support opening links in new tabs, but links that are from the search results used to always open in new tabs and now it's not working for some reason.

Hi,

I have a problem connected with shortcuts on tabs in Mozilla Firefox. When I click a tab with right mouse click then I can for example close tab by just clicking W, or I can pin a tab using P. And it works great on Windows 10. But on my Macbook clicking buttons on keyboard does not do the required action, it just kind of hovers over the option i chose. I mean, when you look on the attached image you can see that for example in "New Tab" letter "w" in underscored (so I can click "w" and then the tab closes). Is there an easy fix for that?

Thanks

I have used Firefox for 10 or 20 years and have not encountered this before.

New computer running Windows 11 Home. New Firefox install. If I am writing a message in any forum or social media site, and I need to look-up some info or the name of a place or product and I use another tab to do that, when I return to the original tab, Firefox reloads the entire page again instead of just returning me to the post that was being written without reloading the entire page. It can be a severe waste of time trying to find the post I was in the middle of once the entire tab reloads when the site is a busy place with lots of new and updated posts.

I've been through Firefox settings but did not see anything that seemed to be related to this issue, but perhaps the wording/description of the needed setting wasn't clear.

Hi I read these articles and they doesnt help to resolve the problem https://support.mozilla.org/en-US/questions/1349609 https://support.mozilla.org/bm/questions/1206172 https://www.reddit.com/r/firefox/comments/ip88y7/firefox_is_preventing_windows_10_from/?rdt=53488

Problem: I have Win10. Firefox 107. I have noticed that if I have opened only regular/textual web pages in my tabs like news/articles then PC goes to sleep after specified time of inactivity. But if I open in the one tab some media content like videoclip/animation/movies and put media content on pause then PC doesnt go to sleep after specified time. PC goes to sleep only by manual command (Start>Sleep). Even If I close the tab with media content PC doesnt go to sleep after specified time. I should or totally close the browser with all opened tabs or manually select Start>Sleep.

Could you help to resolve this issue ?

On the screenshots are shown that some of firefox processes couldn't stop making some activity, every second they make some web request or disk operation. May be this is reason why PC cant go to sleep. But again, this is happen only or some media content is put on pause or some tab with media content has been closed.

Mac OSX 10.13, FireFox 115.1.0esr (64-bit): previously cmd-click on link would open in new background tab. Now it opens the link in BOTH current tab and a new background tab. This has started occurring in the last few days (mid Aug 2023). This is especially a problem when viewing CraigsList where it was very helpful to be able to cmd-click on links of no interest to mark them as "read" while remaining on the main list page. Now it is necessary to back up to previous page (main list) after clicking on each link... Is this perhaps a recent change (I had auto-update turned on)?

Why am I losing my open tabs. I have it set to open where left off.

This has happened about 3 times recently. It is a huge inconvenience as I have multiple windows with a lot of tabs open in each. It is too active and difficult to save them all as bookmarks. I thought if you were signed into your account, that would automatically remember what your open tabs were.

I think it has something to do with clearing history. A couple times that function seemed to stall. Like this time. This doesn't happen all the time though. I can clear data & history, have all my tabs sitting there, and they are restored when I go back in, as usual.

I am going to have to change browsers if this continues because I need all my working tabs, many which I will not even remember, to get back to manually.

I just turned sync on (was reluctant to do that as I don't know all the specifics how it works). My mobile phone open tabs did not wipe out as I feared probably because looks like I'm not signed in there. Might have lost everything there also. But does having sync turned on keep things stored in your account so it can't get wiped out?

I have tried every solution I can find to restore tab separators for 104.0.1—no luck at all. This includes modifying userChrome.css, which is enabled in about:config. I feel bad about having to bring this up, as it seems to have been well-discussed already. But I'm pretty much at wit's end. Maybe I missed something? Hoping to stick with FF, which I've been using for many years. The run-together tabs are a real tough one, though.

See a code here: https://github.com/mozilla/pdf.js/pull/1500/commits

I want , not document.title = pdfTitle + ' - ' + document.title; but document.title = document.title + ' - ' + pdfTitle

Since,

1. The titles of PDFs which I often deal with in my work are usually irrelevant than the content (for example the URL of PDF generators' webpage)
2. changing title to a relevant one is harder than changing just the filename
3. the visible portion of title visible on Firefox tabs is barely enough to display only the title of PDFs

I want to change it. Any help would be appreciated. Any pdfjs setting, viewer.js or any other solution. But no programming skills, so step by step guide will be useful, if any.

Since the last updates, all my tabs appear on multiple rows. How do I get this back to 1 row. And why can't I find anything about this searching help/the internet with such a big change ?

Hello, When I try to arrange my tabs they are not moving smoothly, this is the same problem that mentioned here by another user: https://support.mozilla.org/en-US/questions/1403031

I also tried waterfox, it has same problem.

Unfortunately it is not listed here: https://support.mozilla.org/en-US/kb/how-set-tab-pickup-firefox-view#w_set-up-firefox-view How to switch to firefox view (first tab where all your windows and tabs are) with a hotkey!

When I open a new tab this website opens up instead of a blank tab. "https://search.rspark.com/?ytm"

I've set my new tabs to open a blank page, and I have the current version.
