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.
