Non-functioning Javascript and 24.2 is slow

Hello. I've been using 10.4F for a good while and a couple of things are really frustrating. Any time there's a site that uses Javascript (like yours for the Category dropdown) 10.4F won't work and I have to copy/paste the URL into some other browser to continue. Plus Javascript sites give me an error message saying Javascript must be enabled.

I just had to copy/paste your "discussion" URL into Sunset in order to continue because your site wouldn't let me continue until I selected the appropriate topic from the dropdown. Which I couldn't do because 10.4F wouldn't let me!! The dropdown was non-functional.

Second problem is that 24.2 seems much slower than the previous version. I'm just about to drop it and go back to 17.

    Did you turn JavaScript off? Did you change any settings in about:config?

    Without some specific information on what's slower, I can't suggest anything to you about the speed question.

    Didn't turn JS off, I looked for that ability in preferences but couldn't find it. I haven't opened about:config nor changed anything that way.

    The slower problem: all I did was upgrade from 17 and now it's slower. Didn't change a thing. Slower in all website browsing and typing functions and especially if I have more than 1 or 2 tabs open.

    CPU usage doesn't seem to get much higher than around 60%, often lower. RSize right now is 659MB and VSize is 2.45GB and that's with 2 tabs open. I don't know how to interpret that data but thought it might be useful.

    I can only recommend attempting a profile reset to see if there is a left-over setting or a bad add-on causing this; I don't have anything other specifically to offer you. If JavaScript won't start, it must have been disabled somehow either by an add-on like NoScript or a setting you may have forgotten about. (The ability to disable JavaScript in the Preferences window was removed with Firefox 23.)

    If you want to try this, go to "How to reset your profile" at the lower right.

    If I had turned JS off in Firefox (3.6.2) would that preference have migrated over to 10.4F? If so, rather than completely resetting my profile, I could start FF, change that preference, close it then start 10.4F and it should carry back over??

    Any ideas about the slowdown?

    You could, but that assumes that one particular setting is the problem, and you've apparently got other things going on as well. (If you wanted to try that, I'd use 17 to do it, not 3.6 -- 3.6 has a very good chance of corrupting your profile now.) The slowdown was exactly why I suggested a profile reset instead of a single-setting fix.

    Among other systems I personally use TenFourFox on a 1GHz iMac G4 daily and I don't notice it being particularly slow, especially considering the machine is over a decade old.

    OK, well I guess a profile reset is the best. Not sure what little bits that'll change, I've never done that before.

    What things will it change that I might panic over? And it'll just change the 10.4F profile, not my FF profile right?

    Your Firefox profile is your TenFourFox profile -- by design, TenFourFox is designed to look to the Mac like Firefox so that bookmarks and other settings transfer over. I don't support switching back and forth between Firefox and TenFourFox because Firefox 3.6 has an excellent chance of not understanding the profile format of later versions, and possibly damaging it. By using TenFourFox, it's changed already; it does attempt to upgrade profiles transparently.

    The document explains which things are removed and which are not. Read it carefully before you start since the process is (mostly) irreversible.

    OK. If I ever want to go back to FF, I'd have to mothball 10.4F then reset the FF profile?

    Yes. You probably should delete the Library/Application Support/Firefox folder completely in that case and let Firefox 3.6 recreate it; you should export your bookmarks before, but I'm not 100% sure Firefox 3.6 will read an export from a later version. (I'd just use Camino, personally, which is equivalent to Firefox 3.6.)

    I did use Camino for a long time but FF was so much better particularly in terms of ad blockers that I switched. The different FF ad blockers are completely awesome (not just AdBlock Plus) and I'm sure glad they work with 10.4F otherwise I wouldn't be using it. I never see a single ad on any site I go to including the inline underline ads.

    If have got the same problem, is there any solution yet? All JavaScipt sites wont work... It happens after I ve used 10.4 Fox for some two or three weeks without any change of settings, is the no way to reinstall JS or switch it on somewhere?

    I have no suggestion for you because I can't reproduce this problem on any of my test machines. I'm sure it's upsetting, but I have no way of debugging a problem I can't demonstrate.

    Thanks for the superfast support! I just solved the problem by restarting my profile!

    I'm glad to hear that fixed it. I'll still leave this open for the original poster.

    OK, I'm finally getting around to resetting my profile. I think I'm understanding that if you do that, you wipe out all your add-ons and have to re-download them all.

    Is there some way I can save a list of all my add-ons because I have a bunch. Only thing I can think of is a screen capture.

    All your cookies and passwords will still be there after you do a reset, right?

    A screenshot of the Add-ons Manager is a very good idea. There's no technical way to export a list of add-ons or the add-ons themselves, you need to re-download them.

    The browser will try to preserve cookies, passwords and bookmarks, but it's a good idea to backup your profile folder (~Library/Application Support/Firefox) before resetting.
