Firefox Support Forum

I found when pressing Alt+Enter in the address bar, the link will open in a new tab, which is nice. But if I press Alt+click a link in the page, the link does not open in a new tab (while Shift+click can open in a new window as expected). I'm not sure if it's a problem, but I hope Firefox can have this feature so that opening a link in a new tab can be more convenient.

Besides, in some browsers, drag a link to a nearby place will open in a new tab. However, in Firefox, this manner does not work, unless I drag a link to the tabs bar.

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

When I was voice chatting with my friends, I wanted to screen share a tab in firefox, but I couldn't. It didn't say anything, the only thing I could share was the voice chatting app and my recording software. I was also going to screen share my game so I can show it to my school friends but it didn't show the game I wanted to play. I was also in a tutor and was about to share a tab but there was no tab share option. And yes, i did set permission to share my screen. I don't know how to fix this.

Hello! Since I do not see any options for submitting an enhancement request, I thought I'd do it in this forum. Maybe there is an answer already out there that could get answered here? I am a software business analyst, who specializes in usability and process management. Being one of the older users of Firefox (as are many of us 'old folks') ;), I would like to ask if there is any possibility/functionality of being able to change the tab appearance once you've installed a theme extension? Depending upon the theme installed, the tabs are translucent. This is understandable based on being able to see more of the theme, BUT... For those of us who are older, sight impaired, etc., Often it is difficult to see the words on the tab and which one is highlighted. I for one, usually have multiple tabs open relative to my work. It would be so helpful to be able to choose an option to change the tabs to:

1. 1 Using opaque scale/slider bar (to increase or decrease), or just an option to make the tabs opaque.
2. 2 Change the font to bold if desired.
3. 3 Change the color of the text to white or black.
4. 4 Make the current tab a little more pronounced (i.e., highlighted)

Thank you for your consideration of these development enhancements which would help many users. Should there be an answer out there already of how to accomplish at least one of these requests, (of which I will apologize for I cannot find any info or extension yet), I would be most grateful for your assistance with these options. Cheers!

hi there!

is there a way to open a firefox tab in a new private window? it's something i'm wishing for all the time!

(google posts from many years ago state a way to select this option from the menu, but if it worked it no longer is in the menu.)

my reason for needing this so often is that i have many add-ons that block trackers, ads, etc, which are disabled for my private mode. so if a tab won't load, it would be the easiest way by far to get it to do so!

thanks for any help!

Hello, I am on a MacBook Pro (2015), and I have a problem on all channels of Firefox Occasionally , when I minimize Firefox, the screen blinks/flashes white , even on default themes Can anyone tell me why this is happening , and how to fix it ?

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.

Hello, I would like to close all Firefox windows (to free up RAM) and then be able to restore all windows with their tabs without leaving the session. Is it possible ? Thanks.

Firefox 87.0 Kubuntu 20.04.2 LTS

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.

I have many tabs like 200-300. Firefox crashed today. I also have 4GB page file on top of that. Strange! After I restarted Firefox it was using only 6.8GB RAM. Perhaps memory leak. BTW if I have browser.cache.disk.enable set to false. Is page file still used?

Thanks for help.

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.

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!

Fred

On the New Tab where you can save top sites to save for later and easy access, well i had a few saved there and then something happened and now they are all gone and i'm not able to add anymore, i click add site, give it a title and then put in the url and click add and nothing happens. I don't understand.

I was using Duck Duck Go to search on subjects, and as I was looking at the pages it listed I suddenly could not open any of the links returned at all. I have Firefox set to open links in a new tab, but it stopped working suddenly, and would not open the links at all. Why might this be?

I have this option enabled, so when I open a new tab, it instantly switches to it. This works when I install Firefox, but it stops working later for some reason. I tried to start Firefox in safe mode under another profile (with no addons) didn't help.

Thanks for help!

Today I opened my Firefox and all my tabs are gone. I was able to find a backup in sessionstore-backups, but when I renamed it to "sessionstore.jsonlz4" and replaced the one in the main profile folder, opening Firefox still don't gave me any tabs, just the default "new tab".
