Firefox Support Forum

Hi Folks,

I'm still using an older version of firefox to keep essential add-ons that Quantum no longer had. I'm having problems on a windows 7 computer with the version I have on it, and would like advice on the best way to proceed.

I had copied over my profile from a different computer where I'd been using FF55. I'd had some problems with 55, so I installed 52 on this computer, but using that profile. It's not working very well as I can't get vertical tabs or vertical tabs reloaded to work, it's also crashing fairly often for no apparent reason, etc. Now even the "+" symbol to add a new tab has disappeared from the tab bar, and I don't have a clue why or how to get it back!). For what it's worth, this isn't a malware/virus problem - I'm running McAfee and also periodically malwarebytes etc., and scans aren't finding problems. Computer has been restarted several times and so on, and I'm still having the problems. Could this be because the profile was from a firefox 55 version and it's being used on a FF52 version? Or would that not cause this sort of problem?

I don't want to go to 56 because I gather it won't be able to access my older saved sessions (I use Session Manager and those are the sessions I'm concerned about - so if this is NOT a problem, please let me know). I'm concerned about this because wiki says: "...Another change was the introduction of the mozlz4 format, a proprietary variant of the lz4 compression format (.mozlz4 and .jsonlz4 file extensions instead of .json.lz4 as per unix/linux standard). Session data is stored in the lz4 format instead of plain text. Firefox 56 can not recognize the legacy plain text session files, only the lz4-encoded ones...."

So I'm wondering if I should go to 55 on this computer, or 52ESR? I gather the ESR would have better security - but want to know if there's a difference in add-on compatibility or other features since 52ESR is, I gather, based on older code than 55?

If someone could talk me thru the pros and cons of using 55 versus 52ESR I'd sure appreciate it!!!

Also, I would be VERY grateful if folks could point me towards: 1. a reasonably safe site where we can search and install legacy add-ons 2. any webpage which has a good information showing which legacy add-ons now have reasonable replacements in the current FF version.

Last night around 10-ish my add-ons quit working suddenly. Now I remember something like this happened last month but I also saw it happened to several people so I wasn't worried. But I didn't see a topic about it this time (although I might not have looked well enough?) so I don't know if it's just me.

It won't let me try to install an alternative add-on, and if I right click it'll say to check my connection, but isn't my connection fine if I'm using the internet anyway? Right clicking it says it's a corruption issue.

I've spent days trying to find out if there is going to be a recent (expired certificate) disabled addons fix for older versions of FF? I use v53.0.2 and DO NOT want to update to a newer version. I've read so many posts and solutions but they apply to the latest version download.

Using FF v53.0.2 Win7 32bit

Updates – Last updated 14:35 PST May 14, 2019. We expect this to be our final update.

• If you are running Firefox versions 47 – 56: install This Extension to resolve the expired security certificate issue and re-enable extensions and themes.

Updates – Last Updated: 17:04 EDT May 9, 2019

A less technical blog post about the outage is also available. If you enabled telemetry to get the initial fix, we’re deleting all data collected since May 4. (May 9, 17:04 EDT)

Mozilla CTO Eric Rescorla posted a blog on the technical details of what went wrong last weekend.

Updates – Last Updated: 19:28 EDT May 8 2019

We’ve released Firefox 66.0.5 for Desktop and Android, and Firefox ESR 60.6.3, which include the permanent fix for re-enabling add-ons that were disabled starting on May 3rd. The initial, temporary fix that was deployed May 4th through the Studies system is replaced by these updates, and we recommend updating as soon as possible. Users who enabled Studies to receive the temporary fix, and have updated to the permanent fix, can now disable Studies if they desire.

For users who cannot update to the latest version of Firefox or Firefox ESR, we plan to distribute an update that automatically applies the fix to versions 52 through 60. This fix will also be available as a user-installable extension. For anyone still experiencing issues in versions 61 through 65, we plan to distribute a fix through a user-installable extension. These extensions will not require users to enable Studies, and we’ll provide an update when they are available.

"Updates – Last Updated: 11:51 EDT May 8 2019 (From Mozilla Blog)

Firefox 66.0.5 has been released, and we recommend that people update to that version if they continue to experience problems with extensions being disabled. You’ll get an update notification within 24 hours, or you can initiate an update manually.
An update to ESR 60.6.3 is also available as of May 8th. We’re continuing to work on a fix for older versions of Firefox, and will update this post and on social media as we have more information."

A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).

There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. More information about the remaining issues can be found by clicking on the links to the release notes above. (May 5, 16:25 EDT)

Updates:

Some users are reporting that they do not have the “hotfix-update-xpi-signing-intermediate-bug-1548973” study active in “about:studies”.

Rather than using work-arounds, which can lead to issues later on, we strongly recommend that you continue to wait. If it’s possible for you to receive the hotfix, you should get it by 6am EDT, 24 hours after it was first released.

For everyone else, we are working to ship a more permanent solution. (May 5, 00:54 EDT)

There are a number of work-arounds being discussed in the community. These are not recommended as they may conflict with fixes we are deploying. We’ll let you know when further updates are available that we recommend, and appreciate your patience. (May 4, 15:01 EDT)"

~Pj (Yeah! My Extensions Are Back!)

I updated Flash Player yesterday to the latest version. Now, Firefox instantly crashes when I play a YouTube video. Videos on vimeo and other sites seem to work fine, but on YouTube it crashes (and the entire window is closed down) within a split second.

I have tried disabling flash player, still crashes. It also crashes in safe mode. Other browsers like Chrome works fine, so I assume the problem must be with Firefox. I've sent in a crash report but I'm also looking for answers to fix this here.

Recently, like in the last couple of days, I've had this problem that every webpage that I haven't visited before (like after I've cleared my history) loads twice/instantly refreshes. For example, if I type in 'pineapple' into Google search, the page will load and show me the results, then a split second later it will instantly refresh/load again and show me the same results. This is SUPER ANNOYING and has me somewhat concerned since it hasn't been happening before.

Note, I'm using an older version of Firefox. But it's never been a problem before so I doubt the issue lies there.

Any and all help to solve this problem would be much appreciated.

I have seen the advice about clicking on the 3 dots in the address bar to take a screen shot, but there are no dots in the address bar. I cannot find any other option for taking a screen shot. Is there one I am missing?

hi i decided to revert to FF v53.0.2 because i hated the newest update which has a new toolbar. and now FF seems to hang and stall especially when i'm using facebook. is there a newer version of FF which gave us back the older toolbar? and the othe thing is that exactly one hour after i log onto FF, and every hour thereafter, something refreshes and "updates" for close to 2 minutes. this is extremely annoying and, i think, unnecessary. any clues?

I have a very recent version of Firefox but not sure which because when I call it up I get a blank box that cannot read. I save bookmarks but they do not save. I set my history to keep it forever, and I never have any history. I try to play videos on Facebook and they look like they are loading for a few seconds but then return to the way they were. When I start typing in a url to sites I regularly visit, I get no prompt.

I have tried other browsers, and the sound is fine on them, but there is something wrong with firefox. I cannot hear any video playing. I go to youtube and its silent. I go to my school online module and its silent. There is something wrong with firefox.

I want to highlight certain parts of a that deals with my seizure disorder so that my love one pays close action to it. How do I do this on a website before I print it?

So, i hated Firefox 57 and i had enough of it after using it for about a year and switched back to Firefox 53. Now even after using Snyc and putting the Bookmarks toolbar items on the Bookmark Toolbar, My Bookmarks DON'T APPEAR. Not even Bookmarks i add. It might've been the installer i downloaded but it probably wasn't, well the only thing i can say more is OH EGADS, MY firefox bookmark toolbar IS RUINED (yes that was a joke with the Steamed Hams meme.)

Logging into my yahoo account from my company laptop and an unknown email address autopopulated. It was a Gmail account email. (JPLOxxx@gmail.com) I don’t save history and also checked internet explorer and it didn’t do this with internet explorer. How can this happen? This email is not a contact of mine.

when media starts playing on my computer without my consent, this should be considered a cybercime.

The only way for a video to start playing should be `right click -> play`

cut the nonsense with the *media.autoplay.enabled* switch. it doesnt work and it never will. as soon as the website uses any kind of scripting, this switch is ineffective.

which extension do i need to install to stop this autoplay nightmare forever?

I have new installed os, after a month i instal new firefox. But when i set sycn account, all my bookmarks and password is missing. I think the data will safe on my firefox account, so i didn't create json file backup for my account. How to resolve this? Can you explain why this happen. Did firefox support the could storage for firefox sycn account?
