Firefox freezes when using Audiogon

glad you brought up this topic scott_w. I've had some issues with FF + Audiogon but like another member wrote the issue seems to be better since upgrading to the latest FF version.
For me even worse than Audiogon is Flickr - as I'm cruising thru photos in my various groups FF freezes after scrolling thru about a dozen pix. Then it crashes, pops up a window that says "oops, this is embarrassing your session crashed due to a script that stopped working..."
I've had that same sort of issue streaming shows from CBS's website.

Almarg,
honestly i cannot say if my plugins are up-to-date - i've never made a conscious effort to check. I do update each time i get promoted by Adobe Flash, FF, etc.
Thanks for your advice - i'm going to check them per your suggestions & update them if they are out-of-date.

Almarg, All,
last night i checked my various plugins - the Flash player is up-to-date. the Adobe Reader DC was not. And, a bunch of other plugins such as one from Apple, Google updater, some plugin pertaining to my Canon camera were ’unknown’ to Firefox & it had the ’research’ link next to it. Of course, i’ll be updating the Adobe Reader DC tonight but what about those other plugins that i need to ’research’?
I don’t remember each one of them exactly but can provide a list if that’s required. Thanks for the help.

last night i was streaming a show from CBS.com & it kept freezing. Argh, it was sooooo annoying. Tried several things to fix that - quit the tab & restart, scroll the video back in time & replay hoping it would not get stuck at the same point & the one that worked the best - don’t put it in full-screen mode (which sucked because i had to watch the whole show in a 5X7 mini-screen). I’m pretty sure that the show from CBS.com was using the Flash player (that is up-to-date per FF) yet i had intermittent video streaming.....

Thanks very much Almarg. I'm going to try these 3 suggestions tonight.
after reading the write-up of Flash Protected mode it seems that i'm suffering from exactly the symptoms stated in that article. I;m running Win7 Pro 32-b (& i'm sure many others are as well) & I wonder why some of us are more adversely affected than others??

Almarg,
you reminded me of another thing i need to check - i’ve not done a Win7 update in a while. That could be another potential reason....
Also, last night when i turned on the monitor i was "welcomed" by a popup form that said a security update to FF 44.0.2 is available & that it’s highly encourage. So, i installed it ASAP. Well, I can tell you that FF was working better WITHOUT that security update! I was glad that i had updated to 44.0.2 as many of my streaming woes had disappeared but after last night’s security update they’re b-a-c-k!! :(
Deactivating Flash protected mode scares me a little bit (I’ve been down for 1 month in 2013/2014 when ransom-ware infected my computer. I can thank the children for downloading their games & every free toolbar that came with it!! I realize that Flash protected mode will not save me when I've installed free toolbars or installed free games. Even then once bitten, twice shy...) but i’m definitely going setup Flash to be active when needed + try the safe mode to debug which plugin might be the root cause. also thinking of installing uBlock & Disconnect extensions like some other members have. I was on the ublock.org website & saw that they have a download for FF.
thanks.

Almarg,
this was a security update. I’m looking at the log files & it seems that the message was from FF. The log file in the installation folder tells me it was a ’maintenance service’. The actual log file in the AppData folder has a bunch of PREPARE PATCH xxxx & PREPARE ADD xxx logs. It appeaars it was a legitimate FF security patch for me. Perhaps you’ve already done this security patch since you are so much more on top of this sort of thing compared to me?
Anyway, i’ve told the Flash player to "ask to activate’ & I installed Disconnect & uBlock.
i will monitor the performance with FF from now on & hopefully i’ll be in the same company as bpoletti, tls49, djohnson54, yourself & others.....

wow, i learnt a bit more computer software maintenance on Audiogon! Thanks Almarg for your guidance & thanks scott_w for raising this topic - an illterate (me) is a more literate. ;-)

Almarg, djohnson54,
ok, you guys have me a bit worried now that i got duped by that FF security patch to install.... ;(
As Almarg suggested, I did look carefully at all the programs installed on my machine & nothing seems out-of-order i.e. i can explain each installed program. 
I will run Malwarebytes tonight. I have it installed & have been a user of the free version for several years now. i also have Bitdefender. I've been running them in normal operational mode (not safe mode). I will now run it in safe mode....
thanks once again guys.... 

just letting the experts know that i ran malwarebytes in 'safe mode with networking' *& it did not find threats. i was happy to see this & this might be a good sign...
this uBlock is working really well - all those banner ads on the top of the Audiogon page have all disappeared :-)

thanks djohnson54.
haven't had a chance to stream since Monday but hope to do so today & over the weekend. *if* i still see FF freeze during streaming then i'll know that i still have the issue....
