    Reviewing 36.0.1 (Mar 6, 2015)

    hopefully this release won't have the problem i've been encountering whereby FF does not still stays in memory as shown in task manager and then reports its crashed and has to close after about 30 seconds.

  5. 5 out of 5 stars

    Reviewing 36.0 (Feb 24, 2015)

    I know I've said it a million times but the work that went into many of the previous versions of FF was great. This one has *tons* more performance fixes, updated SQLite that does 20% more work using the same CPU cycles, full HTTP/2 support, fixes to reduce memory use. I admit some of the issues from 35 and before were bugging some but I feel this version has squashed most if not all of the issue. The only complainers are those still using XP. Guys, seriously, it's time to get off of XP.

    This versioning race makes NO sense. It muddies the waters for everyone and is the antithesis of what Mozilla was supposed to be about. A full version upgrade should have substantial changes in multiple areas of a product. At least some of the bugs introduced after v3 are finally being rooted out..I suppose that's "progress".

    Why is some one posting versions of Firefox here using this confusing syntax ?

    Why continue to use a word grouping that leads to flaming?

    This was a problem before and even though a simple rearrangement of terms would prevent problems, some one continues to cause upheaval by placing the Firefox version numbering directly after the word Windows. This practice not only disrupts this site it also harms the reputation of Mozilla Firefox.

    I move to, at least advise, the user who is responsible for this behavior to please adjust the title
    Mozilla Firefox (v6) for Windows, 6.0 Beta 4
    Mozilla Firefox (v6) 6.0 Beta 4 for Windows
    Mozilla Firefox for Windows version 6.0 Beta 4
    Mozilla Firefox for Windows V6.0 Beta 4
    Mozilla Firefox for Windows 7/2000/Vista/XP
    V6.0 Beta 4

    It seems the title breaks badly with the page layout as written so perhaps all these could use adjusting as well

    Dude, if you REALLY think you are so smart and know so much more than everyone else, why don't you be smart enough and download your English release from the directory you show us and install it - then find out what the hell version it is - it's not so difficult to see the "you are running the beta version" or something or another that gets loaded on the first start page of the program. THIS IS A DAMN BETA FOLKS - THE final version HAS NOT BEEN RELEASED!!! Don't install this and then come complain that something doesn't work. This is still BETA!!

    I note in the review of Firefox 7.0a1 that the reviewer was havng problems with XMarks. There is a dev version of them that works perfectly and can be found here -

    That held me back from using it as I do like to link the various versions of Fx but now it is running well - and no crashes (yet)

    On 21 March, FileForum claims to be posting the final release of Firefox 4.0 (i.e., not a release candidate). Mozilla's own FTP site lists that 4.0 final is not yet released and RC2 (released on 18 March) is still the latest.

    Anyone got any ideas as to why 3.6.3 will not open on Vista Home Premium x32? Even 3.5.9 won't open either.

  10. Mar 3, 2010 - 7:54 PM

    I'm sorry, but I do not see the logic in posting an alpha anywhere but the app's home site (Mozilla in this case). This is just asking for bad ratings and general problems.

    If you are having a problem with extensions in an update, you need the nightly tester tools. It will allow you to force an older extension to work.

    I hope they make it better. Lately I am having huge problems with this running just okay. Been using firefox 2 since that seems to be way better.

    Big speedup over currently released Firefox, on the XP machine I tried this on. While the ACID 3 test isn't perfect yet, it's much closer.
