Why for google chrome and firefox the plugin for java AND Shockwave player isn't supported? I mean their both updated-but the plugins won't work or check. Plus when I checked chrome:plugins it has 5 plugins even flashplayer.

@Megan because Chrome 42 drops NPAPI support, i.e. all cross-browser plugins except Flash. It's been announced long ago, in 2013.

@Megan Ryan - There is a way to temporarily re-enable NPAPI support in Chrome. Go to chrome://flags/#enable-npapi and click Enable.

Keep in mind that in September 2015 (Chrome 45) NPAPI support will be permanently removed from Chrome and extensions that require NPAPI plugins will no longer be able to load those plugins. So, this is only a temporary fix.

ok, i have windows 7 64bit,home premium. today when my google chrome updated too version 42.0.2311.90 m.

these plugins no longer appear in its plugin list.
wide vine, vlc, java, silverlight, foxit reader plugin, google earth plugin, photo gallery, google update, unity player, google talk.

i did find something today to tell me how to temporally re-enable this, now they all are showing up, i also know that in september 2015, that in the next version of google chrome(in september) i wont be able to re-enable them again ever.

how ever, for the moment, firefox has them all listed and they work.

Please fix the Bengali font problem in the tab title, omnibar and the 'find' box. The usual fonts are replaced by rectangular blank boxes. Here is a screenshot: http://imgur.com/w3AmQJr

PS: Why haven't you mentioned the changes in your Bookmarks manager? I absolutely loved it!

PS2: Also, please redesign the card in which Chrome shows search suggestions (while typing in the omnibar). Please make it just like it is in Chrome's android version: the card is slightly 'raised'. Also, it would look better, in my opinion, if it takes only some space below JUST the omnibar, NOT the entire toolbar (which contains the back and forward buttons, the refresh button, the omnibar and the menu button.), just like it was in Chrome 27 and prior versions.

10:44 PM, April 14, 2015

PS3: The font problem is occurring in Chrome's Windows 7 versions, but not in Windows 8.

There's another problem: extensions crash. I think all extensions crash while installed from the webstore, but not when installed in the developer mode. Extensions crash every time I start the browser or in the middle of browsing.

The message that is shown in the chrome://extensions page under the crashed extension is

"This extension may have been corrupted."

There appears an option to "Repair" the extension just left to the bin (remove) icon. Screenshot: http://imgur.com/WHLkyo7

Again, this is appearing on my Windows 7 computer, but not on Windows 8.

Google, you better come up with a better solution then what you are going to force us Chrome users on your build that is coming out in September. Sites are not going to bow to you when you disable NPAPI permenatley for plug ins.
There is a lot of coding that goes into plug in compatibility and this is going to cause a major stink.

Great. I used to have probs with facebook-videos. They shuttered and shaked (only FB). I had 2 flash-players in plugins (the normal one and that Pepper one). Always had to deactivate that Pepper-Flash, and videos worked fine. Now the normal Flash-Player is gone, so when i deactivate the Pepper, i can't watch any videos, because there is no other player anymore. And with it activated, they still shutter. So bye-bye FB-Videos. Or bye-bye Chrome...

The new Hangouts app in Gmail.com has broken communication (ie broken sounds) in phone calls.

New hangouts widget in Gmail on windows desktopon chrome browser, not showing ALL phone numbers in search: I am using the new Hangouts widget in Gmail, and am trying to call phone on it by pressing the phone icon. I have thousands on contacts. But when I try to search for a name in the phone number entry field, the search is not showing the desired names, even though the contact exists in Gmail contacts. This used to work fine in the old Gmail phone call widget. Kindly fix this. One can try to see this issue, by having 1000s of contacts in Gmail Contacts, and then try to “search” for that number in hangouts widget in Gmail, while trying to make a phone call from Gmail hangouts. Lots of those contacts will not show up.

If you play games on Zynga.com do NOT update to the newest version if you want to play the games. This version removes all versions of Flash except PepperFlash and it will not allow you to add another version. I cannot play games with PepperFlash or watch videos either as they are too jittery to view. If you want to update, I suggest you find another browser to play the games in because you will get NOTHING done with Chrome 42.

I'm all for modern standards, etc, but why in the world are you removing the NPAPI toggle that the general public is never going to find/use?

Even the most dense person in IT must realize how much of the Enterprise market relies on incredibly out of date Oracle/Java technologies, and your arguments about all the evils of said technology fall flat.

It's like telling homeless people they'd stop being homeless if only they bought a house.

Your approach to the Enterprise market with this issue is high on smugness, and completely void on realism.

Is there a way to prevent Google Chrome from attempting to load all my Tabs on start-up?

It used to be, I would wait a while after opening Chrome, no more than half a minute or so, so that Chrome can cycle through all my Tabs and give an "Internet Connection Error" before turning on my Internet. This stopped it from trying to load all my 90-something Tabs even though I'm not looking at them. Then, I just go to each Tab when I'm ready, and they load as I am ready to look at them, and most importantly, not all at once when I'm not ready.

Now, with this new update, the way it works seems to have changed. Chrome will periodically try to load each unloaded Tab whenever it detects an Internet source, meaning my 90-something Tabs across 2 windows will each try to load, and I'll start hearing a Youtube video from a random Tab start playing and, worst of all, my computer slows to a crawl (plus, my Internet slows down, too, trying to load all those Tabs and the media within).

Is there anyway to go about this? Stop Chrome from loading Tabs on start-up and prevent it from always trying to load/refresh each Tab/page that's not loaded whenever it detects working Internet?

Thanks for any help out there, guys. It'll be greatly appreciated.

The hundreds of folders, alphabetized, sorted, and cross referenced for the thousands of links I have saved for my work was all scrapped in favor of poorly categorized "Auto Folders" or a bulk list. And what I'm supposed to just set all that up again for a fancier bookmark menu? No, thank you and thank you so much to User Hedgehog for the fix. As long as I am able to keep the new bookmarks feature turned off I will stay with Google Chrome.

As Götz Geese says above, where click to play is enforced using Group Policy in a Windows domain environment, you cannot click on a plugin to enable it. No amount of fiddling with the plugin settings in Chrome will enable the plugin to run. A lot of websites still use Flash and this is a major hassle in our environment where we have only recently switched to Chrome and now I have to tell people to go back to IE until this is fixed.

Honest question: How is anyone supposed to watch videos using Chrome 42?

I can understand you choosing not to support a particular kind of code, but where does that leave the average user when they go to YouTube, Vimeo, etc.?

There are helpful strangers trying to explain what to enable/disable and whatnot, but doing that causes other hang-ups and problems in the browser.

Why release a new version of Chrome that can't play videos for the average user?

@Sebastienne I don't understand why you say that watching online videos doesn't work for the average user of Chrome 42. If you're referring to the jitter issue with Pepper Flash, I have never seen it before. I'm sure I am not the only one. Furthermore, Flash use on the web is declining, replaced by HTML 5, which Chrome supports very well. Please share your video player problems in more detail; someone will be better able to help you out.
