Browser preview not working after Tahoe 26.0.1 update Macbook Pro 16"

Dreamweaver 21.6 - Browser preview not working after Tahoe 26.0.1 update on Macbook Pro 16".  Edit Browser List doesn't help, no browser shows up, whether I use the mouse or keyboard shortcuts.

I had the same issue initially and from your screenshot I clicked on Edit Browser List. I was then presented with an error saying I needed to delete all browsers from the list and then re-add them manually. As soon as I did that mine started working again. Are you able to try this with your Mac?

[klaus XYZ]

I reset Dreamweaver preferences and settings first. So, after editing the browser list several times, the preview still does not work—neither via the menu nor via keyboard shortcuts.

Hi! Also having the same issues.

My workaround is to use "open with" (instead of preview in browser) and select the browser manually from Applications.

Please resolve ASAP!

Did you disable Real-Time Preview from your Preference settings?

[GrphcRtst]

For whatever reason, this was not enabled on my end anymore but that fixed it!

Having this same issue since upgrading to Tahoe. Editing the browser list and disabling Real-Time Preview has not resolved the issue.

If the settings are not saving, I would recommend trying to reset preferences next: https://helpx.adobe.com/dreamweaver/kb/restore-preferences-dreamweaver.html

No. The reset didn't help either. On Mac the short-cut Opt F12 and Cmd F12 is used by the Mac operating system for system prefs (Opt F12) and the MacBook speakers (Cmd F12).

On the Mac I have to use additionally the Function or Globe key to trigger F12, for example.

I have the same issue. It suddenly happened with Tahoe. Resetting all preferences would delete all my Project Seven extensions (about 60 or more even), readding will take more than an hour. Is there another workaround? Moreover, also the fav additions don’t work. Adobe should fix that with an update. This issue hasn’t occured since I use DW (many years CS 1 - 4 etc until now. It’s a bug issue and should be fixed with an update or does Adobe force users to delete all of their individual settings because they don’t want to offer a bug fix?

Hi -- The issue isn't specific to a browser. The issue is that when I go to "Open in Browser" in Dreamweaver, I see the list of browsers --Chrome, Safari, Firefox, but clicking them does nothing. Prior to the Tahoe 26.0.1 update, clicking each of these would open a preview of the document in each browser.

[GrphcRtst]

Does not matter what browser

[Nancy OShea]

@GrphcRtst & @ckranz,

Try opening your browser manually outside Dreamweaver. 

Then from Dreamweaver, go to FILE ⇒ OPEN IN BROWSER

Please report what happens on 

Dreamweaver version #, 

macOS version #,

Browser & version #.

[Mijago]

Thank you for your anwser. The issue is with all browsers, Edge, Chrome, Safari, Brave, Firefox …

[Mijago]

This is xxactly the same (mis)behaviour that happens to me!

[Mijago]

Hi @Nayan_Kankariya , thank you for your reply and making me aware. I just found your email in the spam folder and replied to it. I am happy for offering your help and support! Kind regards!

Doesn’t work to open the browser ouside DW and then from within DW.

Doesn’t fix the issue.

(Of course it works to open the html file via Finder directly in the browser.)

DW 21.6 Build 15711,

MAC OS 26.1 (25B78)

BROWSER: what ever version of whatever browser the file can’t be opened from within DW.
