I really like my new window URL, but I only need to see it once a day. The blank page new tab is great for someone like me whose attention gets hijacked by interesting Pocket articles.

I have a link on my toolbar to a text scratchpad URL: data:text/html, <html contenteditable>

It's great for grocery lists, YouTube comments, etc. and if I really need to save the text it's no problem.

Is there a way to turn that URL into the default new tab URL?

Tab cannot be fixed to the left edge. Pinning a tab locks it to the left edge of the tab bar, but it no longer holds. A <mark is displayed at the left end of the tab bar. I can't identify if it's due to firefox settings or add-ons. The version of firefox is 87.0 windows10 64bit I got into this situation after restarting firefox.

When I open the browser, the upper task bar which contains the web sites I most often visit, also opens three totally unidentified web sites that in fact are not recognized web sites since he message related to each is essentially telling me there was a problem opening the site. The identity of the three sites are not configured as web site address, and are identified in the task bar as "problems" How do I get rid of the upper task bar? I do not need it since the regular task bar below the address bar with all the specific features addressing the various options.

So, I've had this problem once already and solved it. Mozilla updated automatically and I lost all of my tabs (over a 100 tabs, mostly with books I wanted to buy / compare prices), couldn't restore the session and had no history. After a dramatic and prolonged freakout, I actually found help on this site and managed to open the correct upgrades.jsonlz4 files with the jeffersoncher scrounger website. I meant to save all of the links in a word file since I no longer trusted firefox to open my tabs after an update, but real life happened. I kept putting it off and was content to have the tabs on hand as a list on the scrounger website. But then ANOTHER automatic update happened and now I no longer find the old .jsonlz4 file - I have a few really old ones (from 2017 and 2019) but the one from around the time period of the first tab loss only has tabs about restoring lost history. I now, just as before, again have no history to find the tabs with the books I want that way. My question is: I would very much like to have those tabs back - some of those books were meant as gifts and finding them the analog way is possible, but very time-consuming. Is there any way I could find the correct .jsonlz4 file (I even remember the date it was modified as shown in file explorer - or should I just give up the whole affair as lost and no longer waste time on it? I'll try reinstalling firefox after I post this message, but given that it didn't work last time, I'm not very optimistic.

Thanks in advance, all the best Ana

Can't seem to recover my session

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

Hey!

First time I get that, I usually lose my tabs due to my mistake but this morning after starting my PC all the tabs were gone with no option to restore or any error message. I backed up my previous session json and other files by hand but every time i copy it back into my profile folder and rename it sessionstore.jsonlz4 it just gets deleted after I open firefox and none of my old tabs get loaded. I scrounged the files before and saw that they contain my lost tabs, I just can't seem to restore them. I tried reinstalling firefox too but that didn't help.

Did the restore system change or is the backup corrupt ? Thanks!

Playing youtube video on Firefox has become a hazard. The power consumption sharply rises whenever a video is plying AND (specifically) when the this youtube tab is the one open (current). As soon as I move to another tab and let the video continue playing this problem disappears and resource consumption looks normal. Then if I go back to the youtube tab then it spikes again sharply.

It has been like this for a week or couple of days now.

When Instagram plays a video and I move to another tab (other than wherein instagram.com is open) then suddenly the Instagram video stops playing completely.

How on earth is this possible in "privacy first" Firefox? When did I gave permission for a video to stop playing just by clicking another tab?

I want a standard HTML5 video to continue to play in any of the tabs that are open regardless of which tab I am clicking-on in the middle of play. Once upon a time that was the case. I want to go back to that state please.

When holding Ctrl and clicking the back arrow at the top left manually, it opens a new tab with the URL of the previous page, as it's supposed to. But for some reason, when I hold Ctrl and press the back button on my mouse, it doesn't do the same. This is quite annoying, as sometimes I need to navigate back, but keep the current page open as well, and this forces me to move my mouse cursor all the way to the top left and back again

Without any difference in functionality the grid view doesn't make much sense to me. For a long time Firefox was the preferred browser on my phone, mainly because it was the only one that supported manual tab reordering. The fact is that I often have a lot of Web pages open in tabs, and I plan to read them later. With Firefox I could quickly set the priority of reading, moving tabs up or down. Suddenly Mozilla made the tabs unmovable and introduced collections instead. Collections are convenient, but don’t replace manual tab reordering. They are great for routine tasks. But on phones, the vast majority of routine tasks are performed by their own applications, so, collections can only be useful for news and forums. However, even while reading the news, I open several tabs that I often need to rearrange. Thus, Firefox became much less attractive to me. Around the same time, Google’s Chrome made tabs movable and even introduced groups of tabs to make browsing more convenient. I recently realized that I now prefer Chrome. I only open Firefox when I need to listen to music videos in background or access my bookmarks and Firefox accounts. Will Mozilla team ever again return manual change the order of tabs?
